Enabled Ctrl-W for readline with changeset
http://hg.savannah.gnu.org/hgweb/octave/rev/e86df0d43309

Concerning Ctrl-S I will have a look at how this is handled.

I agree, big improvement.

Ctrl-W only seems to close the current file in the editor. Otherwise I can't tell that it does anything useful. Can we add this to the list of keybindings that are allowed through in the terminal?

This changeset is a huge improvement.

One last thing, which may be impossible, is my use of <Ctrl-S> mapped to the "Esc" character. I have this key sequence mapped in my .inputrc file which is read by Readline and it works in terminal environments, including Konsole, which I believe forms the basis of our terminal widget.

The difficult thing is that Ctrl-S is often used by terminals for flow control. I don't know who is seeing the characters typed in to the Octave GUI first. Is it Readline or is it the terminal widget?

Can the keybindings change depending on keyboard focus? If the keyboard focus is in the command window, then I think the keybindings should be the same as they would be in a normal terminal window. If the focus is somewhere else, then the keybindings can be different.

I'm in the same minority. I'd prefer to have at least Ctrl-R available, that's the one I've missed so far, not that there aren't others worth having too.

Isn't part of the audience for the GUI going to be people who are used to command-line Octave? They may expect the readline keybindings they used in terminal mode to still work.

I prefer to keep my own readline bindings as well. On the other hand, I also do most of my work using the CLI so maybe I am not the right audience for a GUI.

I'm aware I'm probably a minority who cares about readline, but certain readline keys don't work in the GUI at cset 1ffaad442161. C-n opens a new editor window and C-r results in a parse error.

I'm not sure this really should be fixed or not. The readline keys will naturally conflict with the keybindings that users will expect. I would like perhaps an overall Emacs keybinding theme. I believe Qt provides such a thing.
