Comment #1 on issue 24 by [email protected]: Slow when pressing <SHIFT>
+ O quickly after pressing <ESC>
http://code.google.com/p/vim/issues/detail?id=24
On many terminals, <Esc>O (with an uppercase O) is a prefix for several
keycodes: to see them, do
:set termcap
in Vim running on the terminal where you experience the problem, and notice
that several code sequences begin with ^[O where the blue ^[ means Esc.
I recommend the following setting:
:set timeout timeoutlen=5000 ttimeoutlen=100
where the timeouts are in milliseconds and should be chosen as follows:
timeoutlen: longer than the time it takes you to type successive characters
of a multi-character mapping or abbreviation at your slowest typing speed,
but not too much longer than that, to avoid making you impatient when
waiting for a timeout
ttimeoutlen: shorter than the time it takes you to hit successive keys at
your fastest typing speed, but longer that the maximum time between
successive bytes sent by the keyboard driver for a single (special) key.
