I am switching back to console Vim because it solved the No.1 problem of Gvim:
it doesn't allow another thread to start a X based graphical UI, as it will
clash with the one of its own. Also it now supports true color and is much
faster in responding user ops.
Unfortunately I bumped into the old Alt key mapping problem. After examining
all possibilities I think setting the key codes in Vim is the most practical:
function! s:ConsoleMapAltKey()
let char= 'a'
while char <= 'z'
exec "set <A-".char.">=\<Esc>".char
let char= nr2char(1+char2nr(char))
endwhile
set ttimeout
set ttimeoutlen=30
endfunction
This supposedly should tell Vim that the <Alt-...> key will generate <Esc>
leading key sequences, and enable Vim to tell them apart from user input of
<Esc> followed by other keys by the different time lapse.
This works perfectly under Normal and Command mode, no ambiguity when <Esc> was
pressed, but not in Insert mode, where the <Alt-...> key combination will
always be accepted as one <Esc> followed by another key from the user. I tried
explicitly doing key mapping:
imap <A-s> xxx
and it didn't work. Can anyone enlighten me on this, thanks.
