How can I map "save" to Ctrl + S in Vim?

In Vim, how can I map "save" (:w) to Ctrl + S?

I am trying "map" the command, but xterm freezes when I press Ctrl + X.

If I give Ctrl + V, Ctrl + S, still I see only a ^, not ^S.

Solution

  • Ctrl+S is a common command to terminals to stop updating, it was a way to slow the output so you could read it on terminals that didn't have a scrollback buffer. First find out if you can configure your xterm to pass Ctrl+S through to the application. Then these map commands will work:

    noremap <silent> <C-S>          :update<CR>
vnoremap <silent> <C-S>         <C-C>:update<CR>
inoremap <silent> <C-S>         <C-O>:update<CR>

    BTW: if Ctrl+S freezes your terminal, type Ctrl+Q to get it going again.
