that's what i thought, too. but why does c-s-l work then?

anyway.. wujiangthu - it's not the 's' that doesnt work -
it is the CTRL-S which has a special meaning for terminals.
the CTRL-S is usually the "stop" command for them.
so the terminal "eats" it before vim gets to see it.

if you do use vim within a terminal then you
can unset the "stop" which CTRL-S gives it:
$ stty stop ""

now start vim and you will see that when you switch
to insert mode and type CTRL-S that a "^S" shows up.

however, you might want stop+start with CTRL-S
and CTRL-Q in your terminal at times. if so then
consider mapping command to other key combinations.

as the comma is on the same key with
DE+EN layouts i use ",," for updating:
map ,, :upd<cr>
