One more for the keybindings here (actually, they're more like readline keybindings -- C-h being the biggest difference). I would rather like to know how to set up those keybindings pervasively on graphical Linux applications. (The terminal and Emacs already have them, of course, but not the browser.)

On a related note, I like the command key being solely responsible for most GUI application commands (so it doesn't conflict with the above), and would probably also want to incorporate that into an ideal Linux setup. I wonder if someone makes a Linux distro with this sort of thing preconfigured.
