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>

I'd like to use gvim to view files with long lines. It's a table, so I'm not wrapping the lines.
Is this possible to configure gvim so arrows navigation will be like in "most" tool? Arrow key will move the whole screen 1 character lef/right/top/bottom?
Thanks a lot.
I think this should do what you want.
set nocompatible
set nowrap
set virtualedit=all
nnoremap <Left> zh
nnoremap <Right> zl
nnoremap <Up> <C-y>
nnoremap <Down> <C-e>
If you want the same behavior in insert mode, add the same mappings again as a second set, but use inoremap instead of nnoremap.
The virtualedit setting will allow the cursor to move beyond the end of the line and continue on as if the line had infinite whitespace to the right.
NOTE: virtualedit is only available if Vim was compiled with that feature. You can check with :version. If this feature is available, you should see a + next to it, e.g. +virtualedit.
When I make a .vimrc entry,
nnoremap <silent> <leader>c :colorscheme <tab>
The tab is applied if I understand the terminalogy, as a literal, that is, upon typing ,c, I get in Vim command line,
:colorscheme ^I
I tried to internet the search terms, but mostly I get results about remapping Vim Tabs; the closest I found was somebody putting quotes around their <tab>, but I think that is for a different desired outcome.
I also have this, which is why I want the tab in my shortcut,
set wildmenu
set wildmode=longest:list,full
You'll need the 'wildcharm' option:
set wildcharm=<C-z>
nnoremap <silent> <leader>c :colorscheme <C-z>
See :help 'wildcharm'.
As a side note, I use that option with great effect for switching buffers:
nnoremap <leader>b :buffer <C-z><S-Tab>
and a file-opening variant would be just as easy and just as useful:
nnoremap <leader>e :edit <C-z><S-Tab>
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 really like this vim trick to use the left and right arrows to flip between buffers:
"left/right arrows to switch buffers in normal mode
map <right> :bn<cr>
map <left> :bp<cr>
(Put that in ~/.vimrc)
But sometimes I'm munching on a sandwich or something when scrolling around a file and I really want the arrow keys to work normally.
I think what would make most sense is for the arrow keys to have the above buffer-flipping functionality only if there are actually multiple buffers open.
Is there a way to extend the above to accomplish that?
I'd rather have a completely different mapping because:
cursors are really useful, and not having them because you have a hidden buffer will annoy you a lot
some plugins use <left> and <right> because they are less obfuscated than l and h; those plugins are likely to break with such mappings
Anyway, you can try this:
nnoremap <expr> <right> (len(filter(range(0, bufnr('$')), 'buflisted(v:val)')) > 1 ? ":bn\<cr>" : "\<right>")
nnoremap <expr> <left> (len(filter(range(0, bufnr('$')), 'buflisted(v:val)')) > 1 ? ":bp\<cr>" : "\<left>")
To see documentation on the pieces above:
:h :map-<expr>
:h len()
:h filter()
:h range()
:h bufnr()
:h buflisted()
I use alt-direction to switch between buffers.
nmap <A-Left> :bp<CR>
nmap <A-Right> :bn<CR>
If you modifying hl's defaults, then the arrows would feel more useful. (Like changing whichwrap to allow hl to go past the end of line.)
I do something similar with jk to make them different from my arrows:
" work more logically with wrapped lines
set wrap
set linebreak
noremap j gj
noremap k gk
noremap gj j
noremap gk k
That will wrap long lines and jk will move to what looks like the line below. (If you have one long line, then you'll move to the part of that line below the cursor.) Great for editing prose or long comments.

I map Tab and Shift+Tab to switch buffers when in normal mode (makes sense to my brain and the keys are not doing anything useful otherwise).
Add this to your .vimrc
" Use Tab and Shift-Tab to cycle through buffers
nnoremap <Tab> bnext<CR>
nnoremap <S-Tab> :bprevious<CR>
I have :set hlsearch as default value.
When I search for something, search terms get highlighted. However many times I want to get rid of the highlight, so I do :set nohlsearch. In this way I get rid of highlights for the time being.
However if I do a new search, then search terms are not highlighted.
I would like to hit ESC + ESC to get rid of highlights and then set back :set hlsearch.
Any suggestions?
Try the :noh command.
vi/vim notes
I use
/pleasedisablehighlightthanks
command. Or just
/qewrufhiqwe
But you should be carefult not to mix this with the following command!
/qewrufhiqew
:noremap <silent> <c-l> :nohls<cr><c-l>
This would redraw the screen and clear any search terms with Control-L, handy :) easier than reaching up to the F keys.
I have the following in my .vimrc:
map <silent> <C-N> :let #/=""<CR>
This might suit your needs:
nnoremap <esc> :noh<return><esc>
With a little tinkering you can make it work in insert mode.
Try this:
set hlsearch!
nnoremap <F12> :set hlsearch!<CR>
and hit F12 to clear when desired. Use :noh in command mode to clear.
you could search for something not in the text file. Nothing will be highlighted in this case. (e.g. /349i5u9sgh)
This solution toggles the search:
nnoremap <silent><expr> <c-l> (&hls && v:hlsearch ? ':nohls' : ':set hls')."\n" <BAR> redraw<CR>
