Hi,
I am using vim (console version, _not_ gvim) and mrxvt and of course
zsh, newest stable version on a recent gentoo system.
My problems are keycombinations like ALT-<key>.
Either I start mrxvt as mrxvt and all ALT-<key> are mappes to
<ESC>-<key>.
When using keymappings in vim, which map a keytrstroke to nearly
anthing you want, all mappings using M-<key> are ignored therefore.
vim expsects ALT-<key>s to be in the range of 225-250 and not
keycombos made from <ESC>-<key>. This is also Bram Molenaars, the
author of vim, opinion of how it should be.
Or I start mrxvt as 'mrxvt -m8' instructing mrxvt to generate single
byte keyvalue for the meta-keys as exspected by vim. Then keymappings
in vim of the kind described above do work...but I will loose (for
example) the very handy feature of zsh: pressing ALT-. to get the last
argument of the previous command. Zsh exspects <ESC>-<keys> sequences
for the Meta-keys.
Is there any way out of this disaster ?
Kind regards,
mcc

"bindkey -m" binds the default keys in the other way. Note it doesn't have
a future effect, i.e. anything you define yourself must be defined with
bindkey "\M-..." if you want that effect. Unlike Emacs they're not tied
together, so you need to do bindkey "\e..." as well if you want the
escape version to work. (Hence you don't *need* "bindkey -m" to use
the Meta key if you only want to bind specific sequences of your own.)
With 4.3.2 use "bindkey -m 2>/dev/null"; bindkey -m gives a warning when
multibyte mode is enabled since it will mess up multibyte input. However,
if you don't care you can suppress the warning.
There's a supposedly de-obfuscatory sidebar called "THE META KEY" in "From
Bash to Z Shell" on page 78.

Thanks a lot for your help ! It works and vim and zsh are friends
again. :)
Have a nice evening!
