)Try alias .. 'cd /$cwd:h' in your .cshrc, and then typing .. works.

But that doesn't deal nicely with `cd ../../foo/bar'...
Following is a solution that does _and_ is completely builtin!
Piece of cake right?  :-)

--------------------cut here--------------------
alias	cd	'set tmp=(\!*); eval cd$#tmp $cwd \!*/. ../ ~; echo $cwd'
alias	cd0	'chdir \!$'
alias	cd1	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval cd2 /\!^:h \!:2-:s-../--'\
		'|| chdir \!:2'
alias	cd2	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval cd2 /\!^:h \!:2*:s-../--'\
		'|| chdir \!^/\!:2'
