I'm learning new commands in Vim all the time, but I'm sure everyone learns something new once in a while. I just recently learned about this:
zz, zt, zb - position cursor at middle, top, or bottom of screen
What are some other useful or elegant commands you wish you'd learned ages ago?
I really wish I'd known that you can use Ctrl+C instead of Esc to switch out of insert mode. That's been a real productivity boost for me.
The most recent "wow" trick that I learnt is a method of doing complicated search-and-replace. Quite often in the past, I've had a really complicated regexp to do substitutions on and it's not worked. There is a better way:
:set incsearch " I have this in .vimrc
/my complicated regexp " Highlighted as you enter characters
:%s//replace with this/ " You don't have to type it again
The "trick" here (for want of a better word) is the way that you can use the search to create the regexp (and 'incsearch' highlights it as you enter characters) and then use an empty pattern in the substitution: the empty pattern defaults to the last search pattern.
Example:
/blue\(\d\+\)
:%s//red\1/
Equivalent to:
:%s/blue\(\d\+\)/red\1/
See:
:help 'incsearch'
:help :substitute
I created this reference of my most used command for a friend of mine:
select v
select row(s) SHIFT + v
select blocks (columns) CTRL + v
indent selected text >
unindent selected text <
list buffers :ls
open buffer :bN (N = buffer number)
print :hardcopy
open a file :e /path/to/file.txt
:e C:\Path\To\File.txt
sort selected rows :sort
search for word under cursor *
open file under cursor gf
(absolute path or relative)
format selected code =
select contents of entire file ggVG
convert selected text to uppercase U
convert selected text to lowercase u
invert case of selected text ~
convert tabs to spaces :retab
start recording a macro qX (X = key to assign macro to)
stop recording a macro q
playback macro #X (X = key macro was assigned to)
replay previously played macro * ##
auto-complete a word you are typing ** CTRL + n
bookmark current place in file mX (X = key to assign bookmark to)
jump to bookmark `X (X = key bookmark was assigned to
` = back tick/tilde key)
show all bookmarks :marks
delete a bookmark :delm X (X = key bookmark to delete)
delete all bookmarks :delm!
split screen horizontally :split
split screen vertically :vsplit
navigating split screens CTRL + w + j = move down a screen
CTRL + w + k = move up a screen
CTRL + w + h = move left a screen
CTRL + w + l = move right a screen
close all other split screens :only
* - As with other commands in vi, you can playback a macro any number of times.
The following command would playback the macro assigned to the key `w' 100
times: 100#w
** - Vim uses words that exist in your current buffer and any other buffer you may have open for auto-complete suggestions.
gi switches to insertion mode, placing the cursor at the same location it was previously.
:q!
I wish I knew that before I started vi for the first time.
^X-F completes using filenames from the current directory. No more copying/pasting from the terminal or painful double checking.
^X-P completes using words in the current file
:set scrollbind forces one buffer to scroll alongside another. e.g. split your window into two vertical panes. Load one file in each (perhaps different versions of the same file). Do :set scrollbind in each. Now when you scroll in one, both panes will scroll together. Ideal for comparing files.
You can use a whole set of commands to change text inside brackets / parentheses / quotation marks/ tags. It's super useful to avoid having to find the start and finish of the group. Try ci(, ci{, ci<, ci", ci', ct depending on what kind of object you want to change. And the ca(, ca{, ... variants delete the brackets / quotation marks as well.
Easy to remember: change inside a bracketed statement / change a bracketed statement.
The asterisk key, *, will search for the word under the cursor.
[+Tab will take you to the definition of a C function that's under your cursor. (It doesn't always work, though.)
Don't press Esc ever. See this answer to learn why. As mentioned above, Ctrl + C is a better alternative. I strongly suggest mapping your Caps Lock key to escape.
If you're editing a Ctags compatible language, using a tags file and :ta, Ctrl + ], etc. is a great way to navigate the code, even across multiple files. Also, Ctrl + N and Ctrl + P completion using the tags file is a great way to cut down on keystrokes.
If you're editing a line that is wrapped because it's wider than your buffer, you can move up/down using gk and gj.
Try to focus on effective use of the motion commands before you learn bad habits. Things like using 'dt' or 'd3w' instead of pressing x a bunch of times. Basically, any time that you find yourself pressing the same key repeatedly, there's probably a better/faster/more concise way of accomplishing the same thing.
Some of my latest additions to my Vim brainstore:
^wi: Jump to the tag under the cursor by splitting the window.
cib/ciB: Change the text inside the current set of parenthesis () or braces {}, respectively.
:set listchars=tab:>-,trail:_ list: Show tabs/trailing spaces visually different from other spaces. It helps a lot with Python coding.
ZZ (works like :wq)
And about the cursor position: I found that a cursor which always stays in the middle of screen is cool -
set scrolloff=9999
gv starts visual mode and automatically selects what you previously had selected.
:shell to launch a shell console from Vim. Useful when for example you want to test a script without quitting Vim. Simply hit ^d when you done with the shell console, and then you come back to Vim and your edited file.
This always cheers me up:
:help 42
vimcryption
vim -x filename.txt
You will be asked for a passphrase, edit and save. Now whenever you open the file in vi again you will have to enter the password to view.
Build and debug your code from within Vim!
Configuration
Not much, really. You need a Makefile in the current directory.
To Compile
While you're in Vim, type :make to invoke a shell and build your program. Don't worry when the output scrolls by; just press Enter when it's finished to return to Vim.
The Magic
Back within Vim, you have the following commands at your disposal:
:cl lists the errors, warnings, and other messages.
:cc displays the current error/warning message at the bottom of the screen and jumps to the offending line in your code.
:cc n jumps to the nth message.
:cn advances to the next message.
:cp jumps to the previous message.
There are more; if you're interested, type :help :cc from within Vim.
Press % when the cursor is on a quote, parenthesis, bracket, or brace to find its match.
^P and ^N
Complete previous (^P) or next (^N) text.
^O and ^I
Go to previous (^O - "O" for old) location or to the next (^I - "I" just near to "O").
When you perform searches, edit files, etc., you can navigate through these "jumps" forward and back.
Marks
Press ma (m- mark, a - name of mark). Later to return to the position, type `a.
^r^w to paste the word under the cursor in command mode.
It is really useful when using grep or replace commands.
Until [character] (t). It is useful for any command which accepts a range. My favorite is ct; or ct) which deletes everything up to the trailing semicolon / closing parentheses and then places you in insert mode.
Also, G and gg are useful (Go to bottom and top respectively).
^y will copy the character above the cursor.
Typing a line number followed by gg will take you to that line.
I wish I'd known basic visual block mode stuff earlier. Even if you don't use Vim for anything else, it can be a big time saver to open up a file in Vim just for some block operations. I'm quite sure I wasted a ton of time doing this kind of thing manually.
Examples I've found particularly useful, when, say, refactoring lists of symbolic constant names consistently:
Enter Visual Block mode (Ctrl + Q for me on Windows instead of Ctrl + V)
Move the cursor to highlight the desired block.
Then, I whatever text and press Esc to have the text inserted in front of the block on every line.
Use A instead of I to have the text inserted after the block on every line.
Also - simply toggling the case of a visual selection with ~ can be a big time saver.
And simply deleting columns, too, with d of course.
q<letter> - records a macro.
and
#<same-letter> - plays it back.
These are by far the most useful commands in Vim since you can have the computer do a whole lot of work for you, and you don't even have to write a program or anything.
Opening multiple files using tabs
:tabe filepath
Navigating between open files
gt and gT or :tabn and :tabp
Save the open session so that you can get back to your list of open files later
:mksession session_file_name.vim
Open a created session
vim -S session_file_name.vim
Close all files at once
:qa
Another command I learned recently
autocmd
It allows you to run a command on an event, so you could for example run the command make when you save a file using something like:
:autocmd BufWritePost *.cpp :make
qx will start recording keystrokes. You can do pretty much any editing task and Vim remembers it. Hit q again when you're finished, and press #x to replay your keystrokes. This is great for repetitive edits which are too complex to write a mapping for. You can have many recordings by using a character other than x.
I would have to say that one of my favorites is putting the help window in a new tab:
:tab help <help_topic>
This opens up help in a new tab and, as somebody that loves Vim tabs, this is ridiculously useful.
:x #(Save and Quit a File)
Same as :wq or ZZ
cw
Change word - deletes the word under the cursor and puts you in insert mode to type a new one. Of course this works with other movement keys, so you can do things like c$ to change to the end of the line.
f + character
Finds the next occurrence of the character on the current line. So you can do vft to select all the text up to the next "t" on the current line. It's another movement key, so it works with other commands too.
:b [any portion of a buffer name] to switch buffers. So if you have two buffers, "somefile1.txt", and "someotherfile2.txt", you can switch to the second with simply ":b 2.t<enter>". It also supports tab completion, although it's not required.
Speaking of tab completion, the setting :set wildmode=full wildmenu is also very helpful. It enables complete tab completion for command-mode, as well as a very helpful ncurses-style menu of all the possible matches when using it.

In traditional text editors, whenever I needed to open a string or parentheses and type something between it I used to do:
Type () or ""
Press left
Type in what I need
Press right
But in vim (that is if I followed the vim way) the process becomes quite tedious as I have to enter the normal mode to move a whole bunch of times:
Type () or ""
Press <ESC>
Press i
Type what I need
Press <ESC>
Press l
Press a
If it is not a good practice to use the arrow keys at any time, is there a more efficient way of doing this kind of task in vim?
It is actually quite easy to automatically append those closing characters in a mapping, and put your cursor where you want it. The trick is to do that, without also messing up the undo/redo/repeat actions. The problem is that cursor movement commands in insert mode will break the "undo sequence" so that any change you make after moving the cursor is undone separately from changes made before moving the cursor.
Warning: the following information may become dated
There are plenty of plugins available to automatically append these characters (see the partial list at the Vim wiki page for appending closing characters), and prior to Vim 7.4, some of them even had complicated workarounds for keeping the undo sequence intact. Unfortunately, they all relied on a bug in Vim that got fixed in version 7.4 for this.
A patch is available to add a cursor movement that does not break undo, so if you want to compile Vim yourself, you can grab that patch and use mappings like the following (no plugin required!) to do what you want:
inoremap ( ()<C-G>U<Left>
inoremap <expr> ) strpart(getline('.'), col('.')-1, 1) == ")" ? "\<C-G>U\<Right>" : ")"
These mappings will insert "()" when you type an opening (, placing the cursor in between the parentheses. When you type ')' and there is already a closing ')' after the cursor, Vim will skip over the parenthesis instead of inserting a new one. Cursor movement is preceded by <C-G>U which is the feature the aforementioned patch adds, allowing the following cursor movement to not break the undo sequence (as long as the movement is all in a single line).
As of Vim 7.4.663, this patch has still not been officially included.
No. Doing it in Vim is exactly the same as in your "traditional" editor:
Type () or ""
Press left
Type in what you need
Press right
But… why don't you type the opening character, what you want inside the pair and then the closing character?
Type ( or "
Type what you need
Type ) or "
Too simple?
I think using arrow keys to move around is bad practice in normal mode but in your case; moving one space while in insert mode, I would hazard to say using the arrow keys is probably best practice.
That being said if you are dead set on avoiding them you could use <i_ctrl-o>.
:help i_ctrl_o
CTRL-O execute one command, return to Insert mode *i_CTRL-O*
So, while in insert mode, you could type: ()<ctrl-o>h<xxx><ctrl-o>l, where <xxx> is whatever you want in the brackets.
Unfortunately that doesn't work if you cursor is on the last character of the line, which if you are typing it most likely is.
To solve that problem do :set virtualedit+=onemore or add it to your ~/.vimrc file.
Note that this solution is more keystrokes than simply using the arrow keys but you don't need to move your hands away from the home row so it may be faster anyway.
I am editing a dictionary in a text file, containing Russian words - one word per line.
Some nouns are missing their derivatives, which are usually the same word appended by few more letters - in 6-7 variations as shown in this screenshot:
In Vim I would like to put the cursor in the first column and scroll down line by line. And when I recognize a noun, I'd like to press some (as few as possible!) keystrokes to take that word, copy it in separate lines and append the letters.
I can get rid of the duplicates by issuing %sort u later.
If I could run that command on the whole file it would be something like:
%s/\(.\+\)$/\1^M\1а^M\1ам^M\1ами^M\1ах^M\1е^M\1ном^M/
Do you please have an idea, how to create such a "macro" in Vim?
There are a couple of ways that you can handle this. You can create a macro or you can create a map. Either can be done while running VIM. Either can be placed in another file (your .vimrc, for example, or a file with bindings specific to this project) and sourced when needed.
I will also give you a bit more advice with regular expressions: if you are writing something particularly complex, you can greatly decrease the number of \s needed by starting the regular expression with \v (i.e., :s/\v([0-9a-f]+\s)/0x\1/g).
Creating a Macro in VIM
You can start a macro in VIM by pressing q in Normal mode, followed by the key that you wish to use for the macro. You can then invoke the macro by pressing # followed by the macro's letter. Press q again in Normal mode to stop recording.
You can therefore enter this macro as follows (using the q register):
qq:s/\(.\+\)$/\1\r\1а\r\1ам\r\1ами\r\1ах\r\1е\r\1ном\r/Enterq
Then, when you are on a line and you want to run this command, enter #q from Normal mode.
Storing a macro in a file and sourcing it
When you created a macro in the last step, what you were actually doing was setting the q register. You can check this by entering the registers in command mode. You can instead set this macro in your .vimrc file as follows and it will be available every time you start VIM.
Create the file you want to store this macro in (:new).
Add the following line to the file:
let #q=":s/\\(.\\+\\)$/\\1\\r\\1a\\r\\1b\\r\\1ам\\r\\1ами\\r\\1ах\\r\\1е\\r\\1ном\\r/^M"
(If you yank the line and paste it in VIM with Ctrl+R", there will be a proper ^M character at the end of the line. You'll need to do some manual editing to make sure that it's inside the quotes. Alternatively, you can enter Ctrl+VCtrl+M to enter the ^M character.)
Save the file (:w testmacro.vim).
Source it (:so % or :source %).
Test your macro by typing #q on one of the lines you'd like to do this to.
Later, you will be able to load this macro by running :so testmacro.vim.
Create a Mapping
You can instead create a mapping. The following mapping copies the last word in a given line, pastes it onto the following six lines, and then appends to each of the given lines.
nnoremap <c-j> yy6pAа<esc>jAам<esc>jAами<esc>jAах<esc>jAе<esc>jAном<esc>j
n at the beginning of "nnoremap" indicates that it only functions in Normal mode.
noremap means that this command won't engage in any recursive remapping (whereas with nmap, this could happen).
<c-j> maps to Ctrl+J
yy6p yanks the line and pastes it 6 times.
Aa<esc>j appends to the end of the current line, enters the text (in this case a), exits Insert mode, and moves down a line.
You can enter this command in VIM's command mode or you can store it in a file and load it with the :source command.
Combining Registers with Mappings
You can access a register in your mappings. This means that if you know that entering a given replacement regex will do what you want, you can save that in a register and then enter your command on the current line.
To do this, enter the following commands in a file and then source it:
nnoremap <c-i> :<c-r>f<cr>
let #f="s/\\(.\\+\\)$/\\1\\r\\1a\\r\\1b\\r\\1ам\\r\\1ами\\r\\1ах\\r\\1е\\r\\1ном\\r/^M"
Now you can enter Ctrl+I to run the replacement regex in register f on the current line.
Alternatively, dedicate a few registers to the purpose - let's say a-f.
nnoremap <c-l> yy6p$"apj"bpj"cpj"dpj"epj"fpj
let #a="a"
let #b="ам"
let #c="ами"
let #d="ax"
let #e="e"
let #f="ном
In this case, we're using the ability to press " and the name of a register before hitting a command that uses it, such as paste.
You can record macros by pressing q in the escape mode. For example,
position your cursor on the noun you want to edit.
press qa to start recording macro and store it in register a (other alphabet and digits may also be used for registers) .
do whatever general actions you want to do (copy line, paste, append letters, etc. as in you have tried to show in your search string).
once you are done with the changes, in escape mode press q again.
Your macro is now created in register a. Whenever, you want to repeat your key sequences, just press #a.
Note that you can do anything in recording mode, including any kinds of commands, insertions, cursor movements, and so on. For more information on macros and related options, check out Vim help :h complex-repeat.
Vim registers are shared as place holders for both macros and yanked test; this feature allows you to even save and edit your macros in a file. See this question for details.
Here is a map solution - which copies the line into a buffer and then pastes using p.
The A appends at the end of the line
map <F2> 0dwpo<esc>pAa<enter><esc>pAam<enter><esc>pAax ...etc
If your goal is, when your cursor on a special word, and press something, vim will append different "suffixes" (I hope I used the right word, but you knew what I mean). You could go macro (q). However since you have already written the :s command, you could create a mapping using that command do the same, and it would be shorter.
in command line, you can get the word under cursor by pressing <c-r><c-w>. so you could try:
nnoremap <leader>z :s/<c-r><c-w>/& & &..../<cr>
I didn't write the & & &... part, since I don't know (never tried, I don't have vim under windows. I don't even have windows) if the line break \n could be used here under windows. & means the whole matched part, which in this case is the word under your cursor.
So you just move your cursor to the word, type <leader>z, vim will do the job for you. (if the replacement part is correct :) ).
ReSharper has a nice feature called "extend selection": by pressing CTRL+W (I think this is the default) repeatedly, you select more and more from your current caret location. First it's a word, then more and more words, a line, inner then outer block of lines (for example an if-block), then a function, etc...
Basically, by pressing the key combination repeatedly, you can end up selecting the entire file. I'm sure at least some of you will be familiar with it.
I have just started learning all the intricacies of vim and I don't have enough experience to see how something like this could be implemented in Vim (although I assume it's possible). So my question is meant for Vim gurus out there: can this be done and how?
Update: a bit of a background story. I've been talking to my ex-boss about all the benefits of Vim, and he thinks it's all great. His only question/problem was: does it have "extend selection"? My question so far has been no. So, if someone knows the answer, I'll finally win a discussion :P (and maybe create a new Vim convert:-))
I had a quick go at this problem. It doesn't work as is. Feel Free to make edits and post on the vim wiki or as a plugin if you get it refined.
chances are you'd want to make a g:resharp_list for each language (eg. one for paranthesised languages, etc.)
All that is needed is a marker for the original cursor position :he markers and a timeout autocommand that resets the index.
"resharp emulator
"TODO this needs a marker
"also c-w is bad mapping as it has a lag with all the other-
"window mappings
"
let g:resharp_index = 0
let g:resharp_select = ['iw', 'is', 'ip', 'ggVG']
func! ResharpSelect()
if g:resharp_index >= len (g:resharp_select)
let g:resharp_index = 0
endif
exe "norm \<esc>v" . g:resharp_select[g:resharp_index]
let g:resharp_index = g:resharp_index + 1
endfun
nnoremap <c-w> :call ResharpSelect()<cr>
vnoremap <c-w> :call ResharpSelect()<cr>
"Something to reset on timeout. TODO this doesn't work
au CursorHold :let g:resharp_index = 0<cr>
The answer is yes. Once in Visual mode you can use all the regular navigation methods as well as some extra ones.
Some of my favourites? First hit v while in normal mode to get to visual mode then hit:
iw - to select the inner word. Great for selecting a word while excluding surrounding braces or quotes
w - hit multiple times to keep selecting each subsequent word.
b - select wordwise backwords
^ - select all from current position to beginning of text on line
$ - select all from current position to end of line
I'm sure others here could add to this list as well. Oh and don't forget Visual Block mode C-v try it out in vim with the above commands it works in two dimensions :-)
If you're talking about Vim (and you should be :-), you can start marking text with the v command, then you have all the standard cursor movement commands (and, as you know, there are a lot of them) which will extend the selection, as well as moving the cursor.
Then you just do whatever you want with the selected text.
See here for the gory details.
One would need to write a function that would save the current selection, then try increasingly wide selections, until the new selection exceeds the saved one or selects all text. Some possible selections are:
viW - select word
vis - select sentence
vip - select paragraph
viB - select text within the innermost brackets
v2iB - select text within the next most innermost brackets
ggVG - select all text
I think Jeremy Wall's heading in the right direction. And to get a little further in that direction, you might look at the "surround.vim" script from Tim Pope. A good description is available on github. Or, if you'd rather, get it from vim.org. It'll probably help you do some of the things you'd like to do, though it doesn't seem to have a feature for say, simply selecting within a tag. Let me know if I'm wrong.
Ultimately, what you'd really like is a hierarchy of enclosing text-objects. You should read up on text-objects if you haven't. A nice overview is here. Note that you can grab multiple objects in one go using counts, or do this iteratively (try vawasap}}} from normal mode).
You can also get scripts which define other text-objects, like this one that uses indentation to define a text-object. It'll work for many languages if you're formatting according to common standards, and guaranteed for python.
One annoyance is that the cursor ends up at the end of the visual block, so, for example, you can't easily select everything between some ()'s, then get the function name that precedes them...
...BUT, I just found in this post that you can change this behavior with o. Cool!
I suspect you'll find yourself more efficient being able to skip over intermediate selections in the long run.
Anyway, I'll be curious to see if anyone else comes up with a more general solution as well!
In Rider [on a Mac with VS Mac bindings with IdeaVim], I bind:
Ctrl+= to Extend Selection
Ctrl+- to Shrink Selection
Doesn't clash with any other bindings of consequence and doesn't require a v for mode switching, and easier than Cmd+Option+-> and Cmd+Option+<-
Putting it here as I always hit this question with any Rider Vim selection searches. If I get enough harassment, I'll create a self-answered "How to use Extend Selection with Rider Vim mode".
When I'm opening a new file in Vim and I use tab completion, it completes the whole file name instead of doing the partial match like Bash does. Is there an option to make this file name tab completion work more like Bash?
I personally use
set wildmode=longest,list,full
set wildmenu
When you type the first tab hit, it will complete as much as possible. The second tab hit will provide a list. The third and subsequent tabs will cycle through completion options so you can complete the file without further keys.
Bash-like would be just
set wildmode=longest,list
but the full is very handy.
The closest behavior to Bash's completion should be
set wildmode=longest:full,full
With a few character typed, pressing tab once will give all the matches available in wildmenu. This is different to the answer by Michael which opens a quickfix-like window beneath the command-line.
Then you can keep typing the rest of the characters or press tab again to auto-complete with first match and circle around it.
Apart from the suggested wildmode/wildmenu, Vim also offers the option to show all possible completions by using Ctrl + D. This might be helpful for some users that stumble across this question when searching for different autocompletion options in Vim like I did.
If you don't want to set the wildmenu, you can always press Ctrl + L when you want to open a file. Ctrl + L will complete the filename like Bash completion.
I'm assuming that you are using autocomplete in Vim via Ctrl + N to search through the current buffer. When you use this command, you get a list of solutions; simply repeat the command to go to the next item in the list. The same is true for all autocomplete commands. While they fill in the entire word, you can continue to move through the list until you arrive at the one you wish to use.
This may be a more useful command: Ctrl + P. The only difference is that Ctrl + P searches backwards in the buffer while Ctrl + N searches forwards... Realistically, they will both provide a list with the same elements, and they may just appear in a different order.
set wildmode=longest:full gives you a Bash-like completion with:
suggestions in a single line
Tab completing only what is certain
Right/Ctrl-n | Left/Ctrl-p to select suggestions.
From the help:
If you prefer the <Left> and <Right> keys to move the cursor instead
of selecting a different match, use this:
:cnoremap <Left> <Space><BS><Left>
:cnoremap <Right> <Space><BS><Right>
Try using :set wildmenu. Apart from that, I'm not sure what exactly you're trying.
Oh, yeah, and maybe try this link: link
What are the essential vim commands? What does a new-user need to know to keep themselves from getting into trouble? One command per comment, please.
What I find irreplaceable (because it works in vi also, unlike vim's visual mode) are marks. You can mark various spots with m (lower case) and then a letter of your choice (eg x). Then you go elsewhere, and can go back with ``x(backquote letter) to the exact spot, or with'x` (apostrophe letter) to go to the line.
These movements can be used as arguments to commands (yank, delete, etc). For example, you want to delete 10 lines; instead of counting and then moving to the topmost line and entering 10dd, you go to either the start or the end of the block, press mm (mark m), then go to the other end of the block, and press d'm (delete apostrophe m). If you use backquote instead of apostrophe in this example, then the deletion will work character-wise, not line-wise. Try marking in the middle of the line with "mark m", moving to the middle of another line, then entering "d backquote m" and you will see what I mean.
I was very happy the day I learned about using * or # to search, down or up respectively, for the word under the cursor. Make sure to :set incsearch and :set hlsearch first.
I like this QRC!

When you have some repetitive action to take Macros are usually faster than regex.
Just type
q[0-9a-z] in normal mode
Many people use
qq
because it's fast.
Press
q in normal mode
again to stop recording.
Then just type
#[0-9a-z] in normal mode
to repeat what you just recorded.
#q
for the example like above.
Edited to add: you can also repeat the macro. Let's say you programed a macro to jump to the head of a line, insert a tab, and then jump down one line. You then test your macro by typing "#q" to run it once. Then you can repeat the action nine more times by typing "9#q".
:q -> quit
:w -> save
:q! -> quit and don't save
:x -> save and quit
:[number] -> go to line number
G -> go to end of file
dd -> delete line
p -> "put" line
yy -> "copy" line
:s/[searchfor] -> search
I guess those are the basic one to start from
Use the 'J' (J for Join; upper-case) command to delete the newline at the end of a line. You'll find it tricky otherwise.
This recent Vim tutorial from IBM is pretty good
First of all you need to know how to close vi:
ctrl-c : q!
Rest can be found from vimtutor. Launch vimtutor by typing vimtutor at your command line
Although this is a matter of personal preference I've found that one of the essential things to do is to remap Esc to something else.
I find it very uncomfortable to reach for the Esc key to exit insert mode, but the beautiful thing about Vim is that allows key mappings.
I'm currently using the following mapping using Control + S:
inoremap <C-s> <Esc>:w<CR>
This has the advantage of being a key mapping I have already committed to memory and has the added value of saving my work every time I go to normal mode. Yeah, I know it is crazy but I would be hitting the save command that frequently anyway. It's like a bad habit, you know.
" ~/.vimrc

If you're using vim, the 'u' command (in command mode) will Undo the last command you typed. You can use this command repeatedly to undo mistakes you may have made before saving the file.
See http://www.rayninfo.co.uk/vimtips.html for a great collection of Vim tips, from the basic can't-live-without to very sophisticated stuff that you might never have thought of trying.
Lots of great commands are listed at the Vim Tips Wiki.
It's also good to run the vimtutor when learning these commands
alias vi nedit :)
all humor aside..
for vi WHEN NOT using nedit..
i (switch to insert mode)
a (append = move to end of line and switch to insert mode)
esc (exit insert mode)
dd delete a line
x delete a character
:wq (save and quit)
/ start a search
n find Next
? search backwards..
yy (yank) copy a line to the buffer
pp (paste) paste it here
r (replace a character)
<N> <command> this is a neat - but aggravating feature that lets you type digits and then a command so
5dd will delete 5 lines
but at this point you might as well
- man vi and refresh your memory
While there are LOTS more, I switched from Vi to nedit several years ago, which I find has more features I can use on a regular basis more easily. Tabbed editing, incremental search bar, column select, copy and paste. sort selected lines, search and destroy within selection, whole doc or all open docs..
tear-off drop down menus..
and it supports syntax highlighting for all the languages I use.. (with pattern files I've used a long time over the years. VIM many now be equivalent, but It has to introduce a feature that Nedit doesn't and an easy way to migrate my pattern files before I switch again.
I like the Vim 5.6 Reference Guide, by Bram Moolenaar and Oleg Raisky.
You can directly print it in booklet form, easy to read, I always have it laying around.
It's a tad old, but what are 8 years in Vi's lifespan ?
:set ignorecase smartcase
Makes searching case-insensitive, unless your search includes a capital letter. Not the most indispensable perhaps, but I find myself setting this option any time I'm editing in a new place. It's in any vimrc file I own.
:%!xxd
View the contents of a buffer in hexadecimal. To revert:
:%!xxd -r
My biggest tip: ctrl+q saves the day when you accidentally hit ctrl+s to save the file you are working on
I have this in my vimrc
set number
set relativenumber
This gives me a line numbering system which makes j, k keys really productive.
I use vi very lightly, and I only use the following commands:
a - switch to insert mode (after the cursor)
esc - return to command mode
:wq - save and quit
:q - quit (no save, only without modification)
:q! - force quit (no save, also with modification)
x - delete one character (in command mode)
dd - delete the whole line (in command mode)
I know there are many many more, but those are enough to get you by.
One of my favourite commands is %G which takes to directly to the end of a file. Especially useful in log-files.
How to switch between modes (i to enter insert mode (one of many ways), esc to exit insert mode, colon for command mode) and how to save and exit. (:wq)
Another useful command is to search something: /
e.g. /Mon will search (and in case of vim highlight) any occurences of Mon in your file.
As a couple of other people have already mentioned, vimtutor is the way to go. It will teach you everything you need to know in vim. The one piece of general advice I would give you is to stay out of insert mode as much as possible. There is enormous power in the other modes, it just takes a little bit of practice to get used to it.
i - insert mode (escape to exit)
dd - delete line
shift-y - 'Yank' (copy) line
p - 'Put' (paste) line(s)
shift-v - Visual mode used to select text (tryin 'yanking' this text and 'putting' it somewhere.
ctrl-w n - create new window (you can open a file or start new file here)
ctrl-w v - split existing window vertically
ctrl-n (in insert mode) - autocomplete (if supported)
:! to run a shell command, usually with standard in as the file or a selection (shift-V)
Useful plugins to look at:
* Buffer Explorer - use \be to view files in the buffer (and select to re-open)
NB vi is not vim! vim is rapidly turning into the emacs of the new century. nvi is probably the closest thing to the original vi. Here's a nice hint: "xp" will exchange two characters (try it).
replace 'foo' with 'bar' everywhere in the file
:%s/foo/bar/gc
The real power is in the searching. Here are the essential commands:
/Steve will find the first instance of "Steve" in the text.
n will find the next "Steve" in the text.
:%s//Stephen/g will replace all those instances of "Steve" you just searched for with "Stephen".
Not to promote myself, but I wrote a blog post on this subject. It focuses on the critical parts of Vim for a beginner.
My favorites:
% find matching bracket/brace
* and # next/previous match
gg top of page
G end of the page
<Ctrl-v> Change to visual mode and select column
<Ctrl-a> increase current number by 1
<Ctrl-x> decrease current number by 1
