Map escape+s to save file in vim

Question

I want a shortcut to save the current file in Vim. I want to map escape+s to :w. I tried

:map <esc-s> :w

but it doesnt work.

In case you weren't aware, this will obscure a vim function. s in normal mode deletes the character under the cursor and enters insert mode.
You are mixing two native vim commands to do the work of another native vim command. :w is better than <Esc>s because it doesn't force you to reach for the <Esc> key.
Marty: Well i didnt know you could do that with s. I have mapped <C-s> to :w now. Had to tweak the terminal for that though. romainl: I have escape mapped to my caps lock so its not a problem

Try,

:map <Esc>s :w

Or perhaps,

:map <Esc>s :w<CR>

<CR>, <Enter>, and <Return> are the keycodes for the return/enter key.
