I am a new vim user and I try to play around a bit. I am trying to have an efficient way to code a block with figure brackets :
{
blabla;
....
blabla;
}
So the first thing I did is put the following in my .vimrc to get the opening and closing bracket when I write a opening bracket :
noremap <silent> <C-S> :update<CR>
vnoremap <silent> <C-S> <C-C>:update<CR>
inoremap <silent> <C-S> <C-O>:update<CR>
And to start writing within the brackets, I then hit :
"i" "enter" "enter" "esc" "ciw"
Seems a bit tedious, what do you think?
There was already another thread on this topic: Automatic closing brackets for Vim
Alternatively, you can try out a plugin, such as: delimitMate
inoremap { {}<Left>:
To open a closing } right after the cursor
inoremap { {<cr>}<c-o>O
To open a closing } below the cursor. Maybe you want to set autoindent to.

inoremap <C-i> <Esc> " cntrl-i to switch to normal
nnoremap <C-i> a "cntrl-i to switch to insert
Tried the following to have cntrl-i toggle between normal and insert modes. However, when I toggle into insert mode it works but pastes everything after a, this happens also when replacing a with i. It fails completely when in insert mode and just inserts a tab.
Alternatively if anybody has better suggestions for a mapping to toggle between both, I'm all ears. I wanted to do caps lock however couldn't find a mapping for it in the vim docs.
Dont put comments after maps:
inoremap <C-i> <Esc>
nnoremap <C-i> i
For a quick overview, I map <s-space> to <esc> so I can more easily cancel out of things without moving my hand to the escape key. For example, when I want out of insert mode, or to cancel something.
inoremap <esc> <nop> " to force me to stop using <esc>
cnoremap <esc> <nop>
nnoremap <s-space> <nop>
onoremap <s-space> <esc>
inoremap <s-space> <esc>
However, if I press 'r' vim is waiting for a character, and when I press <s-space>, I end up replacing with a space, instead of canceling the replace operation. Is it possible for mappings to work after pressing 'r' once, while waiting for a character?
Thanks!
If you find you've accidentally pressed r, how about just tapping uu?
This will make the replacement but immediately undo it again, without you having to move your hands from the letter keys.
I like highlighting while searching in vim. Here's what I want:
I search for a word with /
Then, all of the results are highlighted. If I press any key other than n or N, I want the highlighting to be toggled off.
If I press n or N again after any number of commands, I want to toggle on the highlighting.
Where do I start? I'm not even sure what to google.
I have this in my .vimrc
nnoremap <CR> :noh<CR>
so that when I'm done seeing the highlighting, I just hit enter to remove it. It stays gone until I hit n or N again.
Note: If you want to keep the functionality of enter, add another <CR> on the end of the command.
I remap control-l (lower case L) so that it clears the search result as well as repaints the screen. This line in .vimrc does it:
nnoremap <silent> <C-l> :nohl<CR><C-l>
You can manually disable the last highlight with nohl.
I will let you know if I can figure out how to automate this.
One method is to setup a toggle mapping. These are some toggle mappings I have in my .vimrc:
let mapleader="\\"
noremap <silent> <Leader>th :set invhls hls ?<CR>
noremap <silent> <Leader>tn :set invnumber number ?<CR>
noremap <silent> <Leader>ts :set invspell spell ?<CR>
noremap <silent> <Leader>tw :set invwrap wrap ?<CR>
To toggle highlighting just type \th for toggle hls. The others are line number, spell checking, line wrapping. The final hls ? will display the new mode.
I prefer this, because to me it is nothing but natural.
Start searching with /<pattern> and once done, simply type <Leader>/ to stop the highlighting.
nnoremap <silent> <Leader>/ :set nohl<CR>
Right now I am using:
nnoremap <cr> :nohlsearch<cr><cr>k
But after I press Enter my cursor goes to beginning of line.
I have additional <cr>k because I want to use default <Enter> behaviour for example when I try to open file in Ack results quickview.
If you want Enter to keep the default behavior, then this mapping should take care of it.
nnoremap <CR> :nohlsearch<CR><CR>
It turns off search highlighting, moves the cursor down, and only applies to normal mode.
An alternative approach is to locally override the new behavior in the quickfix window and the command-line window, where <CR> has special meaning:
:nnoremap <CR> :nohlsearch<CR>
:autocmd BufReadPost quickfix nnoremap <buffer> <CR> <CR>
:autocmd CmdwinEnter * nnoremap <buffer> <CR> <CR>
I am a long time emacs user learning Vim. Emacs lets me navigate in the mini-buffer (where I issue commands like C-x C-s) using the same navigation keyboard shortcuts as in any other buffer. For example, I can navigate forward one character using C-f, even while in the mini-buffer. I could also use the arrow keys, but they are too far away.
Is there any keyboard shortcut to navigate in Vim's command mode (:), without using the arrow keys -- equivalent to emacs C-f, C-b? Thanks.
Adding to Greg Hewgill's answer, you can use q: to open the command-line window, where you have any Vim editing power at your hand.
Some from the Vim help:
CTRL-B or <Home>
cursor to beginning of command-line
CTRL-E or <End>
cursor to end of command-line
CTRL-H
<BS> Delete the character in front of the cursor (see |:fixdel| if
your <BS> key does not do what you want).
<Del> Delete the character under the cursor (at end of line:
character before the cursor).
CTRL-W Delete the |word| before the cursor. This depends on the
'iskeyword' option.
CTRL-U Remove all characters between the cursor position and
the beginning of the line.
I have these in my .vimrc
cnoremap <C-a> <Home>
cnoremap <C-e> <End>
cnoremap <C-p> <Up>
cnoremap <C-n> <Down>
cnoremap <C-b> <Left>
cnoremap <C-f> <Right>
cnoremap <M-b> <S-Left>
cnoremap <M-f> <S-Right>
With the default key bindings, vim does not offer non-arrow-key navigation of the command line editing. However, see :help cmdline-editing for an example of how to use the :cnoremap command to set up alternate key bindings.
I achieved that with <C-p> and <C-n> to navigate previous and next commands respectively.
P.S I'm not making any custom binding like Tassos did.
