Vim in shell allows
<alt>[a-z] to circumvent having to press Esc to get out of INSERT mode. For example,
Open up a terminal and set its editing mode away from emacs, to vi
set -o vi
Now enter INSERT mode and start typing:
<i>[Type some words]
Before you press enter, hold alt, and press "u" for undo:
This will take you out of INSERT mode, and will undo your last change.
If I try to do this in GVIM,
<left alt><u> will type "õ". I would rather have it the other way.
How can I achieve this? Thanks.
