Hi,
I now work with a directory structure that nests very deep; some times
10 to 15 levels. And I do a lot of 'cd ../../' on traversing. I was
checking out something that might help me entering the repeated '../'.
I noticed I might benefit from bind -x command, which could be used to
trigger a shell command when a particular key is pressed. My intention
was, if I could do a 'cd ../' with a key stroke, then I could prefix
that keystroke with an argument (alt+n) so that I could do away with
this long 'cd ../../../../'. Sadly, my bind -x is not working as
expected.
I did:
bind -x '"\M-p": cd ..' and nothing happens; and "\M-p" is still bound
to: non-incremental-reverse-search-history
Can somebody point out what's going wrong here please. Or is there any
other better way?

Many possibilities!
An idea using a function:
$ d(){ [ "${1//[0-9]}" ]||eval "for x in {1..$1};do cd ..;done";}

This perhaps is better than the previous one,
only need d ENTER digit (one digit, 1-9):
d(){ read -n1 _D&&eval "for x in {1..$_D};do cd ..;done";}
Thanks; that's cool. Any idea about the bind built in?
$ bind -x '"\M-p": cd ..' # don't worked for me
$ bind -x '"\C-p": cd ..' # this is fine
/tmp/buildk/
k7-2.6.21.3$
/tmp/buildk/k7-2.6.21.3$
cd .
/tmp/buildk
$
/tmp/buildk$ cd .
/tmp$
But the prompt don't change, I need a "cd ." to change it.
If you need change the PWD between 2 or 3 dirs a funtion
with vars D1, D2,D3 can be a easy way to up and down to
specific points. The bind + function can be used if you like.
Sorry, I don't know anything about bind and my english is poor.

If you're ready to switch to zsh (which I'd recommand), you
could do something like:
rationalise-dot() {
if [[ $LBUFFER = *.. ]]; then
LBUFFER+=/..
else
LBUFFER+=.
fi
}
zle -N rationalise-dot
bindkey . rationalise-dot
If you type
cd ..
then press "." another time, it will turn into:
cd ../..
basically, it transforms "..." to "../.." on the fly while you type.
