C-LEFT doesn't work under cygwin

[klunko@iszf.irk.ru [IMAP]]

Hi, all!

I'm a newbie in vim. I'm trying to use it under OpenSUSE 11.0 as well
as cygwin (WinXP prof. sp3). Unfortunately I found out that cygwin
version doesn't move cursor through the words with CTRL+LEFT, CTRL+RIGHT
(while SUSE version does). I tried to append the folowing lines to
.vimrc file:

map <C-left> w
map <C-right> b
imap <C-left> w
imap <C-right> b

but it had no effect. I also tried uppercase variant:

map <C-LEFT> w
map <C-RIGHT> b

with the same negative result.

The following is an output of :version command.

In that case, you should first test if Vim sees the codes: in Insert
mode, hit Ctrl-V (or Ctrl-Q if your Ctrl-V is remapped to the paste
operation) followed by the key in question.
- If something appears in your edit buffer, but your mapping doesn't
work, then the problem is probably with your 'term' setting or its termcap
- If nothing appears, it probably means that the OS (including keyboard
driver and anything between it and the user application) is not passing
that keypress event to you.

In Insert mode, when I press Ctrl-V first time, the ^ symbol appears.
The second Ctrl-V results in V char. So multiple Ctrl-V results in
^V^V^V^V^V^V^V
When I press Ctrl-Q nothing appears!

No. Try pressing CTRL-V *once*, then pressing Ctrl-Left. The idea is
that by doing this, you will see exactly what Vim receives from the
keypress.

The point is to verify that Vim receives the keypress at all, and if
it does that it is what Vim expects.

See :help i_CTRL-V for details on what we are asking you to do.

That's weird...it's supposed to be a synonym for Ctrl-V.

I see however from :help i_CTRL-Q that "some terminal connections may
eat CTRL-Q, it doesn't work then." Maybe that's what's going on with
your CTRL-Q.

Out of curiosity, why are you mapping ctrl-LEFT to go one word to the
RIGHT and vice-versa? (FYI, the reverse should work out-of-the-box)

Are you using right-to-left text or something?

Also, your imaps wouldn't work even if Vim was receiving the <C-Left>
properly. You want "imap <c-left> <c-o>w" and "imap <c-right> <c-o>b"
instead. Otherwise, you'd just insert a w or b character into the text
with your mappings. See :help i_CTRL-O.

Excuse me!
Pressing Ctrl-V followed by Ctrl-Left results in four chars ^[[D
- the first two ^[ are blue and the last two [D are white.
But I have no idea what they mean.

You're right, I mistook. Of course, C-left should be mapped to b.

You're right again! Now I enter the following commands
imap <c-left> <c-o>b
imap <c-right> <c-o>w
but they don't work too.

^[ in blue means Ctrl-[, i.e., the Esc character. The whole result means
that when you hit Ctrl-Left, the sequence of interfaces between the
keyboard hardware and your Console Vim sends the three bytes Esc [ D (or
0x1B 0x5B 0x44) to represent that keypress.

Tony.

Thank you, but how I can now map this three bytes to <c-o>b ?

Based off :help :set-termcap, this might do it. Give it a shot:

:set <c-left>=^[[D

(where you get the right-hand text by typing, in sequence: CTRL-V ESC
[ D)

I use something similar to fix my ALT keys in PuTTy.

That doesn't look promising. They look like the ANSI codes for regular
cursor keys, i.e. the same as if you pressed it without control. You can
verify this using the CTRL-V trick: see if CTRL-V LEFT gives something
different to CTRL-V CTRL-LEFT. I suspect it won't.

In that case you'll have to investigate options of the terminal program
you are using? Which are you using? The default thing that comes with
Cygwin? I don't know Cygwin well, but does it have some options? See if
it has any to do with terminal emulation, or control keys. Or
investigate trying a different terminal program.

That your CTRL-Qs are eaten isn't a surprise at all if you are using
some program that indeed does emulate a terminal. CTRL-S is probably
eaten too. You can possibly get Vim to see them if you issue

stty -ixon

prior to starting Vim, if indeed that command exists in Cygwin.
