I am trying to set the scroll distance to 3 in Vim. This is what I have tried in my
.vimrc file.
setlocal scroll=3
autocmd VimEnter,BufRead,BufNewFile,BufWritePre,BufWritePost * setlocal scroll=3
None of this works, or it only works for some time and then it stops working when I
change the tab or I make other actions. The error seems to happen randomly or at least I
haven't been able to find any pattern.
Apparently, I am not the only one having this problem.
My temporary solution is to use <C-e> and <C-y> instead with these mappings:
nnoremap <C-e> 3<C-e>
nnoremap <C-y> 3<C-y>
I'm sure someone has a good explanation of why this is happening, though.

there is a strange Phenomenon of my vim(gvim).
just as i said in title, when i press enter, it'll show ^M at lower right. and disappear after about 1sec, then it'll act as it should be. as if it's the first charactor of some "multi-charactor" command.
here are some lines in my vimrc.
au FileType * nnoremap <buffer> <CR> <C-]>
let mapleader = "\<space>"
set encoding=utf-8
set fencs=utf-8,ucs-bom,shift-jis,gb18030,gbk,gb2312,cp936
set fileencodings=utf-8,ucs-bom,chinese
set ffs=unix,dos,mac
can someone tell me how to fix it?
thanks for Pinpin. but my problem occurs in normal mode.
thanks for any help :)
For internal reasons, <C-M> is the same as <CR> (or <Enter>). The reason that Vim briefly displays the key in the bottom right corner is that it is waiting for further keys (and you have :set showcmd), because you have a mapping that begins with Enter.
:nmap <CR>
(or :nmap <C-m>) will list it. To avoid the delay, you need to get rid of it / choose another key for it.
Ok so basically the way Vim highlights searches displeases me. Basically you do a search, then you have to type /asdf or have a shortcut like this in your vimrc:
nn <silent> <leader><space> :noh<CR>
Which is what I have. But it's still too much mental work. Basically, when I do a search, I want highlighting to enable (like it does now) but if I do anything other than cycle through the searches (with n/N) then I want highlighting to turn off. That's basically my workflow, so I'm wondering if I can automate it. Also if I search, do something other than n/N (which should turn highlighting off) and then press n/N again, it should re-enable.
Any ideas?
That's difficult. One idea is
:autocmd CursorHold * call feedkeys(":noh\<CR>")
(One needs to use feedkeys() because :nohlsearch is ineffective in functions and autocmds.) This clears the highlighting whenever you pause the cursor for some seconds. You can add other triggers like InsertEnter or CursorHoldI.
What does not work is CursorMoved, because the searches and n / N jump as well. You would need to overload those commands, store the cursor position after the jump, and modify the autocmd to only clear the highlighting when the position is different.
What I do: I have Enter mapped to :nohlsearch; it's quick and easy to reach.
you can turn it on or off with:
:set hls
or
:set nohls
I have F7 mapped to set hls!:
noremap <F7> :set hls!<CR>
When I leave insert mode by pressing Esc, there is a half-second pause before Vim actually returns to normal mode.
Normally this wouldn't be an issue, since pressing a normal mode command like j after pressing Esc executes the normal-mode command immediately (without the above-mentioned wait), but I have the mapping inoremap <Esc> <Esc>:w<CR>, so that every time I leave insert mode the file is written. I would like the write to occur immediately when I press Esc, but instead there is that half-second pause.
I'm assuming that the pause is because Vim is waiting for more input before it decides that I just meant to type a single, simple Esc. This must be because there is a mapping somewhere who's first character is <Esc>, but I've looked in my .vimrc and there is no such mapping.
Furthermore, I even ran :map <Esc>, and it returned No such mapping. So, if there is no such mapping, why does Vim appear to be waiting for more input, and how can I avoid that behavior?
Extra Information
It appears that this is not reproduceable, so here is some more information in case anyone really wants to get to the bottom of this:
I am using Steve Francia's spf13 distribution of Vim, with my own .vimrc.local on top of it. I have also installed several additional plugins using Vundle.
Notes: .vimrc.local is sourced last in .vimrc.
UPDATE (3/19/2014)
I found a far better solution than trying to hunt down all the mappings that start with <Esc>, courtesy of Powerline, from the Tips & Tricks section of the docs. Put this somewhere in your .vimrc:
" leave insert mode quickly
if ! has('gui_running')
set ttimeoutlen=10
augroup FastEscape
autocmd!
au InsertEnter * set timeoutlen=0
au InsertLeave * set timeoutlen=1000
augroup END
endif
Note that this will make it impossible to use mappings that start with <Esc> while in insert mode, but there shouldn't be any of those anyway, because of the problem this solves.
I found the lines in spf13's .vimrc that were causing the problem:
" Fix home and end keybindings for screen, particularly on mac
" - for some reason this fixes the arrow keys too. huh.
map ^[F $
imap ^[F $
map ^[H g0
imap ^[H g0
The reason I couldn't find them before is because they weren't mapped using <Esc>, but ^[ instead. Very irritating! Hope this helps some equally disgruntled spf13 user :)
UPDATE:
If removing those mappings doesn't work, then it's probably a mapping from a plugin.
Type :verbose map <Esc> to get a list of all mappings involving Esc. The verbose part instructs Vim to print where the mapping was set. That should help find out what's causing the problem.
Also, the command unmap <Esc> might be useful—it removes any mappings for the Esc key.
Note that unmap does not remove mappings in all modes; type :h unmap for more info.
In my case, it was tmux injecting that delay (this came as a complete surprise for me!).
I fixed it by adding set -g escape-time 0 to my tmux.conf.
This may not strictly help the author, but this question comes up first when searching for this issue with many different keyword combinations, so I hope it helps someone.
Source: first comment from here.
I'm not exactly sure what the problem is with the mapping you describe, in my opinion it should be fine. However, I think that what you want to accomplish can be reached in a better way. Your mapping is basically an attempt at creating a InsertLeave event, which Vim actually already has built in!
Try adding something like this to your .vimrc:
au InsertLeave * if &mod && expand('%')!=''|write|endif
As an added bonus, this one only saves your buffer if it has a filename and was actually modified.
set timeoutlen=1000 ttimeoutlen=0
timeoutlen - mapping delays.
ttimeoutlen - key code delays.

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>

Vim clear last search highlighting
(32 answers)
Closed 3 years ago.
I search for "nurple" in a file. I found it, great. But now, every occurrence of "nurple" is rendered in sick black on yellow. Forever.
Forever, that is, until I search for something I know won't be found, such as "asdhfalsdflajdflakjdf" simply so it clears the previous search highlighting.
Can't I just hit a magic key to kill the highlights when I'm done searching?
:noh (short for nohighlight) will temporarily clear the search highlight. The next search will still be highlighted.
Just put this in your .vimrc
" <Ctrl-l> redraws the screen and removes any search highlighting.
nnoremap <silent> <C-l> :nohl<CR><C-l>
/lkjasdf has always been faster than :noh for me.
" Make double-<Esc> clear search highlights
nnoremap <silent> <Esc><Esc> <Esc>:nohlsearch<CR><Esc>
Then I prefer this:
map <F12> :set hls!<CR>
imap <F12> <ESC>:set hls!<CR>a
vmap <F12> <ESC>:set hls!<CR>gv
And why? Because it toggles the switch: if highlight is on, then pressing F12 turns it off. And vica versa. HTH.
Append the following line to the end of your .vimrc to prevent highlighting altogether:
set nohlsearch
*:noh* *:nohlsearch*
:noh[lsearch] Stop the highlighting for the 'hlsearch' option. It
is automatically turned back on when using a search
command, or setting the 'hlsearch' option.
This command doesn't work in an autocommand, because
the highlighting state is saved and restored when
executing autocommands |autocmd-searchpat|.
Same thing for when invoking a user function.
I found it just under :help #, which I keep hitting all the time, and which highlights all the words on the current page like the current one.
I think the best answer is to have a leader shortcut:
<leader>c :nohl<CR>
Now whenever you have your document all junked up with highlighted terms, you just hit , + C (I have my leader mapped to a comma). It works perfectly.
I search so often that I've found it useful to map the underscore key to remove the search highlight:
nnoremap <silent> _ :nohl<CR>
I think this answer in "Vim clear last search highlighting" is better:
:let #/ = ""
There is hlsearch and nohlsearch. :help hlsearch will provide more information.
If you want to bind F12 to toggle it on/off you can use this:
map <F12> :nohlsearch<CR>
imap <F12> <ESC>:nohlsearch<CR>i
vmap <F12> <ESC>:nohlsearch<CR>gv
I have this in my .vimrc:
nnoremap ; :set invhlsearch<CR>
This way, ; will toggle search highlighting. Normally, the ; key repeats the latest t/T/f/F command, but I never really used that functionality. I find this setting much more useful, because I can change search highlighting on and off very quickly and can easily get a sense of where my search results are, at a glance.
Also, if you want to have a toogle and be sure that the highlight will be reactivate for the next time you search something, you can use this
nmap <F12> :set hls!<CR>
nnoremap / :set hls<CR>/
I add the following mapping to my ~/.vimrc
map e/ /sdfdskfxxxxy
And in ESC mode, I press e/
