Once, a long time ago, I bound "\C-k" to "cd .."
and I never looked back. It's easy to type and
easy to repeat. And with the current directory in
the prompt (RPS1 in my case) it's very easy (and
very fast) to go up high enough but no further in
the directory tree (without having to count
directories).

Neat trick though... :-)
