Effective way to put ; at the end of line - vim

Sorry for a noob question, but i find it struggling to just put a ";" at the end of line after writing a function. For example, I am coding in C and many time i need to write things like:
f(a);
what i usually type is (from normal mode, using bracket autopair-like feature):
if(a<ESC><SHIFT-a>;
and it need changing mode twice! Comparing to normal editor (sublime):
f(a<right>;
does anyone have more efficient way do do those typing? thanks for any help.

I think you have some "auto-close" plugin installed.
I have that kind of plugin too, and I don't press arrow keys either, since I don't have them on my keyboard. I have this:
" moving cursor out of (right of ) autoClosed brackets
inoremap <c-l> <esc>%%a
So with your example: it would be (assume already in INSERT mode)
f(a<ctrl-l>;
Thus, your fingers never leave the home row.

If you're a vim user, you can hit Shift-a.
Shift-a takes you from normal mode to insert mode, and starts your cursor at the end of the line.
(If you want to be an efficient vim user, you should remap esc to something like caps-lock.)

Comparing to normal editor (sublime):
f(a<right>;
Well… that's exactly how you would do it in Vim if you use Delimitmate or some other "autoclosing" plugin. Why do you insist on making things more complicated than they are?

Add whitespace to current line in vim

I fairly often find myself in a situation like this:
I'd like to start typing on the line on which my cursor is currently. However, in order to get to the correct indentation level, I'd have to press TAB several times.
Usually I'd press ddO (delete current line and insert a new one above the cursor), which resets my indentation position to the right place:
But that seems like an odd way to go about adding the correct amount of whitespace.
Is there a better way that I'm overlooking?
When in normal mode, you can use cc or its synonym S. If you are already in insert mode, Ctrlf is the default key for this, but that can be changed by altering cinkeys (see :h cink for details).
See also this answer on the Vi/Vim stack
Kevin mentioned some shortcuts, but another method is <C-i> (indent) and <C-d> (dedent) in insert mode.

Pasting text in vim. A tedious operation?

I've been using vim for somewhat longer than a year now and during this time I have never feel really comfortable with the way vim works with yanking and pasting text (or maybe it is just me not using it in the most efficient way)
For example, I have the word "World" yanked onto a register, and I want to paste it after "Hello". (Note that there are no spaces on either of the words). So, what I would do is
Hello
|
Place cursor here, and press "p". Then, what I will end up with is
HelloWorld
So, in order to avoid this, I have always to swith into insert mode, insert a espace, and go back into normal mode (or either make sure that the yanked word has a space before it). Be as it may, this is quite annoying behaviour I can't think of a solution for... Am I missing something here?
Suggestions will be appreciated.
Thanks
option zero
just live with what you have now.
option one
create a mapping for your workflow. for example
nnoremap <leader>p i<space><esc>p
option two
:set ve=all
then you could move your cursor to anywhere and paste
option three
you could in insert mode use <c-o> do normal mode stuff or <c-r> to get register values
I recommend option zero
You can use the Smartput : Adjust spaces and commas when putting text plugin for that. It modifies the p / P commands (this can be toggled on / off).

How can I map these five keyboard actions to a single key in Vim?

I want to map a key so that it will do the following actions in Vim. Suppose I am editing a file; I want it set up so that if I press F2, I will accomplish the same thing I would if I did the following:
press ESC
type colon (:)
type w
press Enter
press ESC again
type i to go back to insert mode
Is this possible?
Yes it's possible, but it doesn't do what you want if the cursor is at the end of line.
To get file saved on F2 in insert mode, use the following mapping:
:imap <F2> <C-O>:w<CR>
Literal answer: Yes. You can use this:
:inoremap <F2> <Esc>:w<CR>I
but it won’t do exactly what you want (the cursor will be at the wrong place).
Anton beat me to the less literal (but correct) answer.
The best answer, though, is this: Don't use Vim incorrectly. You should never spend so much time in insert mode that you need a shortcut to get out of it, save the file, and then get back in. With all other editors, you’re in “insert mode” all the time, and only temporarily pop into a menu or dialog or whatever; in Vim, you should learn to reverse this. Only pop into insert mode to edit or add something; never use arrow keys to move the cursor while in insert mode; spend the majority of your time in command (normal) mode, and after a bit of adjustment to the new paradigm, you will find that your editing speed has increased.
Writing the mapping is almost easier than your description.
First, you need to determine from which mode the mapping will be used, because that determines what :map variant you will use. You’ll probably want to use this in insert mode, so you’ll use :inoremap.
The format of the mapping is:
:..noremap {keys} {rhs}
You want <F2> (see :help key-notation) for keys. For {rhs}, just concatenate the keys listed in your description.
To persist the mapping, add it to ~/.vimrc. (See :help vimrc.)
P.S. The alternative given by Anton Kovalenko is probably better for what you’re trying to do, but here I’ve given you the general recipe for future key mappings.

backward-kill-word in vim?

is the quickest way to go back and kill a word Esc or Ctrl-[ and db? I guess I mess up a lot :P and am used to using M-<backspace or Ctrl-<backspace> in other editors (or word processors). Still getting the hang of this (vim), but switching to normal-mode for short tasks like this one seems an odd way to go about it. Just wanted to inquire if there was anything better than what I was doing... Thanks much ~
In insert mode you can use CTRL-W to undo the most recently typed word.
Are you looking for <c-w> in insert and command modes ? (like in unix shell command line) Or db in normal mode?
Try control + W
Depending on where is your cursor positionned, <c-w> or db won't delete all of the word.
try dib / dab to select the all word (with or without space) regarless of where you are in the word.

Vim: transitioning from mouse to movement

I use MacVim (and gvim) a lot. I'm familiar with and use a lot of the basic movement commands (b, w, $, 0, G). However, for a lot of things—such as selecting particular lines on the screen or jumping to a particular column in a different line—I use the mouse (sometimes in concert with my left hand on the keyboard). It also helps that my mouse has a scroll wheel and buttons for changing tabs.
I also need to admit... I use the arrow keys on my keyboard rather than hjkl.
I think that my speed (and posture at the computer) will be improved by not having to escape from insert mode, and from keeping both hands on the main part of the keyboard.
What convinced you to abandon the mouse? What are the most helpful shortcuts for moving quickly between lines and columns, scrolling, etc.?
This question is inspired by this recent post

having to escape from insert mode
No, you must escape from insert mode right after you typed what you want. It quickly becomes a reflex, so you don't really lose time (I sometimes even press escape after completing a web form...). Normal mode isn't just for moving around, it's used to perform most operations (save from typing): for instance deleting or moving sections of text. You also benefit from entering insert mode with the appropriate key: o to start a line, S to replace a line (while keeping indentation), A to move to the end of the line, c+motion to replace a few words or until a given character... All of these save keystrokes.
The mouse seems fast, but in reality it isn't precise, so you lose time (in addition to the constant back and forth with the keyboard). ViM has a long list of moving commands (see :help usr_03) which, when mastered, are faster than the mouse in most situations.
Use search the most you can (/, ?, *, #, f, t...). I personally use Ctrl+(d,u,f,b) a lot. Also, Ctrl+(o, i) and `` are really useful to go back where you were before a search or something else.
h, j, k, l are there to place your right hand near to useful commands (i, u, o...): I always have my fingers on them. The arrows force you to move your hand a lot.
Try to look at a few commands in :help, then use them a lot, and you'll get habits about what you should use to move according to the situation. Nobody uses ViM the same way.
The more I used the keyboard movement in vim, the less I wanted to use the mouse. It doesn't help that extended periods of time where I'm constantly moving from keyboard to mouse can take a toll on my wrist.
If you want to force doing things the vim way, unplug your mouse for a while! The more you use the keyboard, the more you will love it. This worked for me.
For moving between lines, I usually just use jk but I often skip to lines using :line_num. Getting to a specific column in a line, I typically use wbe^0$ and put modifiers in front of w, b, or e if I'm skipping through several words. And there is also the shifted versions, WBE which also come in handy often.
I have to admit that I often use the arrow keys for specific movement in vim.
I rarely use hjkl. However, I find that most of my navigation is done with other commands such as w (skip a word forward), b (skip a word backwards). Combine this with modifiers such as 3w (3 words forward). : skip to a specific line.
I've never really had to abandon the mouse since I never really started with it. All I can say is that attempting to use editors without all the keyboard shortcuts that vim has can feel quite painful.
I'd run vimtutor from the command line (Terminal.app in OS X). It runs vim with a tutorial document. That document was what really made me realize the power of some of the commands. You'll pick up some that are most useful to you and gain more over time. Eventually you'll find yourself using the mouse less and less.
One command that will really improve your movement speeds is f. f plus a character will jump to the first occurrence of that character on the current line. Pressing ; will jump to the next occurrence. Of course this can be used in combination with other commands. So, for example, removing all characters up to and including the first closing parenthesis is achieved by pressing d+f+).
You can seriously revolve your life around jk in hjkl.
nnoremap <c-k> ddkP "move current line up one
nnoremap <c-j> ddp "move current line down one
vnoremap <c-j> dp'[V'] "move visual block down one
vnoremap <c-k> dkP'[V'] "move visual block up one
"These may be a bit more esoteric to me"
inoremap jj <esc>o "Insert mode can move to next line (works mid line)
inoremap kk <esc>O "Insert mode new line on previous line
also for the desktop gui (ion3 and gnome)
winj - next window
wink - prev window
(This beats alttab if your editing in vim all day)
also read :he motion.txt in its entirety using j and k to scroll up and down as you do.
I learned vi so for me the mouse has never been something to use with a text editor.
I don't use hjkl except when the machine/network/keyboard/whatever-in-between is not comfortably configured.
Use the mouse where it makes sense. It often does (copy/paste to and from other gui applications).
To answer your question, though: Once you start using vim as a tool for transforming text bits with macros, the movements will all start to fall into place ;)
I think you're wondering if there's a quick way to move around while in insert mode (without using the mouse or arrow keys) but unfortunately there isn't; you have to escape out of insert mode. However I know that jumping all the way to your Esc key can be really annoying, which is why I've gotten into the habit of escaping with Ctrl+c, it's much faster.
I almost never use hjkl because it's too tedious. I usually try to jump right to where I want to go. There's a great cheat sheet out there (a Dvorak version is a available also (although it's in PDF)) that you can stare at and imagine the possibilities.
Mostly I use f, F, t, and T, and sometimes they're enhanced by typing a number up front like d2t) will delete up to the second close paren. Sometimes I use search. A lot of the time I use w, W, b, B, e, and E. They're all fantastic.
When I see vim users arrowing all over the place in visual mode just to delete text it makes me shudder, because there are so much easier ways (and hjkl only make you move your arm less, they don't change the number of button presses).
Something I did that I don't know if it's common or not is remapped my arrow keys to be <Esc><Up> and so on. For whatever reason I started out always arrowing around and assuming I'd be back in normal mode, so I just made it do that...
The biggest bummer about Vim is that now when I edit anything anywhere else I hit escape all of the time and type :w after every change...
