On my mac in the gui in Octave 3.8. I can't access the history at all w. C-p, C-n or the arrow keys.

I'm using the binaries from octave forge.

Sure, I'm closing it.

Can this bug be closed? The issue is with Readline, not Octave. Furthermore, it doesn't seem to be a bug that a certain key combination enters vi mode.

jwe: You're right, that's what it has done. Seems to be an incomplete implementation of vi editing mode though.
I was actually looking for this option after Jordi told me it existed; I inadvertently found it (and didn't even realise) :)

This doesn't work for me. Tried all the various combinations (C-x k, C-x C-k, ESC C-x k, ESC C-x C-k, etc). I'm expecting some kind of output, right? A list of keybindings?

Is it possible that you entered readline's vi editing mode? By default, that is bound to ESC C-j and ESC C-m. You can see the keybindings with C-x k. Unfortunately, the emacs-editing-mode command is not bound to a key by default, so I don't know how to exit the vi mode and return to emacs mode unless you add a key binding for the readline emacs-editing-mode function in your ~/.inputrc file.

I've had this happen too, very rarely, on Debian. It's like readline completely dies. I don't know what causes it either.

Occasionally (unable to pinpoint exact circumstances), I stop being able to access my command history.

Neither the arrow keys nor readline commands work. Readline commands just give ^A, ^E, ^P, ^N etc input on screen. Arrow keys give no output.

e.g.
^G then <enter> in this situation gives me a system bel as expected; this does NOT work when on a working (i.e. arrow keys/readline commands working) window.

This only seems to happen on one install, on XP SP3. I have a similar install (same version of Octave) on a Vista and a Win7 install. Don't have another XP install to test on.

Octave was installed using the binary installer here: http://s3.amazonaws.com/mlclass-resources/software/Octave-3.2.4_i686-pc-mingw32_gcc-4.4.0_setup.exe
