PATCH: customisable menu selection keymap

PATCH: customisable menu selection keymap

[Pete Hollobon]

Hi,

I wanted to use a custom keymap for certain menu selections (in
particular with cd - , to choose a directory from the stack and change
to it by pressing enter once rather than twice).

These two patches seem to do the trick:

That then lets me use my special keymap only for directory completion:

bindkey -N pete_menuselect
bindkey -M pete_menuselect '^M' .accept-line

# Use menu selection on directory stack completion
zstyle ":completion:*:directory-stack" menu yes 'select=0'
'keymap=pete_menuselect'

Is this likely to be useful to anyone else?

Thanks,
Pete
