Here are some of my favorite .vimrc lines.
Save quickly from any mode by pressing CTRL+:
imap <C-\> <Esc>:w<Cr> map <C-\> <Esc>:w<Cr>
Make indenting and de-indenting in visual mode preserve the selection:
vnoremap > ><CR>gv vnoremap < <<CR>gv
Quick case insensitive search with double slash or double question mark:
map // /\c map ?? ?\c
Make the j and k keys move up by a line on the screen rather than a line in the file (very useful when navigating a long line that has wrapped many times):
map j gj map k gk
Highlight column 80 (Vim 7.3+ only):
if v:version >= 703
set cc=80
hi ColorColumn ctermbg=Gray ctermfg=Black guibg=#404040
command Skinny set cc=73
command Wide set cc=80
endif
Don’t show the splash screen:
set shortmess+=I
Keep the cursor 4 lines away from the top or bottom to automatically preserve context when editing near the top or bottom of the window:
set scrolloff=4
Make CTRL+u and CTRL+d less confusing:
map <C-u> 10<C-Y>10k map <C-d> 10<C-E>10j
Scroll the screen with ALT+{j,k}:
map <A-j> 2<C-E> map <A-k> 2<C-Y>
Easy paste toggle:
" Allow middle-click pasting of large texts in terminal set pastetoggle=<F5> " Clear paste mode when going back to normal mode au InsertLeave * set nopaste
Switch windows quickly with CTRL+{h,j,k,l}:
" This breaks backspace in a terminal, but I never use backspace in normal mode
map <C-h> <C-W>h
map <C-j> <C-W>j
map <C-k> <C-W>k
map <C-l> <C-W>l
" This would break in a terminal where ^H is backspace.
if has("gui_running")
imap <C-h> <Esc><C-W>h
endif
imap <C-j> <Esc><C-W>j
imap <C-k> <Esc><C-W>k
imap <C-l> <Esc><C-W>l
