And, as noted in someone else's earlier article, ESC _ works in vi mode.

There are, though, subtleties with $_:

		$ cd /tmp
		$ tee a b c < /dev/null
		$ /bin/csh
		% echo ?
		a b c
	>>>>	% echo !$
		echo ?
	>>>>	a b c
		% exit
		$ /etc/ksh
		$ echo ?
		a b c
	>>>>	$ echo $_
	>>>>	c
		$ exit
		$ exit
