MacVim-like keyboard shortcuts in gVim

Question

MacVim has some nifty features like Cmd + S to save Cmd + Z to undo, and so on, is there a port like this for gVim.

Answer 1

You can accomplish this using the map command in your .vimrc (or _vimrc in windows) like this (Ctrl+s to save):

map <C-S> :w <CR>
map! <C-S> <ESC> :W <CR> i

The later is for when you are in insert mode. You can find more information here Mapping Keys

Answer 2

These shortcuts are not standard vim shortcuts. However, undo is simply "u" and save ":w" (after entering the right mode with ESC).

See eg. this question on how to create your own shortcuts.
