There is.

One thing that Emacs has taught me is that I don't really want to move
up three lines or forward five spaces. I want to move to the previous
paragraph, to the start of the function, the next closing brace. There
are functions for all that. And within a history, I don't really want
to go up three or four or however many history items. I want the
history item where I wrote a complex command to plot a 3d surface. So
I isearch backwards. C-r is the keychord in readline which Octave uses
in order to accomplish this.

I suppose there are some times where you really do want to have a
history on the left of your screen populated with trivial and useful
commands, but more often than not, the trivial commands are cruft and
take up screen space, and you at least remember part of the complex
command, which you can recall easily with C-r.

Yes, I know it's a lot of work. I'm sorry I never got around to
finishing the packaging. Now I'm confused, though. Looks like Rafael
got around to doing it, but I don't see the package in the archives.
Do you know what happened?
