	Those of us who (sensibly! :-) ) use vi have:

		set editing-mode vi

	in our .inputrc files.

	Then <esc> puts you into vi editing mode whence ``/'' searches
	``forwards'' and ``?'' searches ``backwards'' --- with the convention
	that the most recent command is the ``top'' of the file.

	And then when you've found the command that you want, you can edit it
	(with vi syntax) before pressing <return> to re-issue the command.

	No home should be without one.

		cheers,
