I am new at Vim, and the transition from Sublime to Vim is being really hard. I want to know if there's a shortcut to add a new line above or behind the current line while I'm in insert mode without leaving it. In sublime I used
cmd + Enter
cmd + Shift + Enter
to do but I didn't find a similar way to do it on vim.
I found the way to do it in normal mode using 'o' and 'O' and also configuring this amazing way http://vim.wikia.com/wiki/Insert_newline_without_entering_insert_mode
but none of them reach what I need.
Thanks !
Defining a shortcut for adding line below is easy, just type the following on the Vim command-line (after typing : in normal mode) or add it to your vimrc file:
imap <C-Enter> <Esc>o
That adds an insert-mode mapping (imap) so that Ctrl-Enter will leave insert mode, then use o to add a new line after the current line (leaving you back in insert mode where you started). (<C-xxx> is how Vim represents the special key sequence Ctrl+xxx, and <Esc> is the Escape key).
That's very similar to the "amazing way" you link to, but just using the appropriate key sequence to go from insert mode to normal mode and then add the line. The way to create shortcuts in Vim is to build them up from smaller pieces. If you know about O and o then all you need to do is create a mapping to get into normal mode first then use them.
From that, it should be obvious how to do the other mapping too:
imap <C-S-Enter> <Esc>O
(<C-S-xxx> means Ctrl+Shift+xxx)
Those mappings work fine for me in gvim GUI but may not work in the terminal-based vim, as the key sequences might not get passed correctly from the terminal to vim. Use some other mappings such as Ctrl+o if necessary.
I use vimgrep a lot to navigate in files and usually use the last search from the history to modify the search pattern and run it again.
Is there a way to display in the command line an editable string like the one below, with the cursor already positioned between the two search pattern slashes (and the pattern being empty)?
:vimgrep // **/*[ch]|copen
I don't want to use a constant mapping (like the one at this vim tip) since I want to be able to add/change options (\c etc.).
I'd recommend using the command-line window for this (q: opens it from normal mode), since you
can edit the command with the regular normal mode keystrokes (and you get syntax highlighting too).
You can also move around in your history just like in a normal buffer. So ?vimgrep<Enter>nnn... will search for and move you to all your old vimgrep commands.
Just hit <Enter> as normal when you are done editing, or :q<Enter> to abort the command and quit the window like you would any other.
Finally, here's a mapping to quickly bring up your empty vimgrep template in the command-line window.
:nnoremap \v q:ivimgrep<Space>//<Space>**/*[ch]<Bar>copen<Esc>F/;i
Reference: :help cmdline-window
Say, I just ran this command in Vim:
:nmap <CR> <C-]>
And now I want to copy this line and put it into my .vimrc.
How can I select and copy the whole line in command-line mode?
The fastest way is to run the command, switch to the destination
buffer (with .vimrc loaded, in this case) and paste the whole
command from the : register by typing
":p
in Normal mode.
If the command is further back in time, one can first recall it from
history (e.g., by typing the first few letters and pressing the up
arrow key ↑), rerun it, and then use the above method.
When these shortcuts are unhandy, one can resort to the general
approach of using the command-line window (see :help cmdwin).
To open it, either type q: in Normal mode, or press the key
combination set by the cedit option (Ctrl+F,
by default) in Command-line mode.
You can type Ctrl-F while in command mode to open up a special window with all previous commands. Then you can scroll to the desired line, hit yy to copy that line, then press Ctrl-C to return to command mode, and then ESC to return to normal mode. From there you can paste.
See :help cmdwin for more information on the command window.
How to make VIM to always auto-complete filenames in command mode? It works fine when I type for example ":cd /ww[Tab]", but if I want to open a file and type ":o /ww[Tab]", it inserts "^I" character instead of completing.
Try:
:e /ww[Tab]
Use ":e" or ":split" or other edit commands instead of ":o".
Bonus fact: vim doesn't really support the ":o" command, at least not according to the docs. ":help :o" says this:
This command is in Vi, but Vim only simulates it:
*:o* *:op* *:open* :[range]o[pen]
Works like |:visual|: end Ex mode.
{Vi: start editing in open mode}
:[range]o[pen] /pattern/ As above, additionally move the cursor to the
column where "pattern" matches in the cursor
line.
Vim does not support open mode, since it's not really useful.
For those situations where ":open" would start open mode Vim will
leave Ex mode, which allows executing the same commands, but updates
the whole screen instead of only one line.
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.

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
