So I took a look at cmd.doc and found a following: > "ESC O not bound" should have been the give-away. Your arrow-keys are generating ^[Ox, not ^[[x. JOVE isn't as powerful as emacs. But it's fast and small and does most of the things in a reasonable way. The latest version has the following in the system-wide initialization file: make-keymap ansi-codes bind-keymap-to-key ansi-codes ^[[ bind-keymap-to-key ansi-codes ^[O bind-to-key previous-line ^[[A bind-to-key next-line ^[[B bind-to-key forward-character ^[[C bind-to-key backward-character ^[[D It creates a keymap called ansi-codes and binds that keymap to two differernt keys, "ESC [" and "ESC O". Then it binds the commands as you would like. NOTE: Binding with the sequence ^[[x binds it for ^[Ox as well, since they are sharing the ansi-codes map. You are right, it is a pain to bind arbitary sequences like those generated from the sun keyboards. Fortunately for me I hate function keys about as much as I hate arrow keys. The reason the arrow keys haven't been bound in the past is that I wanted to discourage people from using them. It's much better and faster to use the ^U command to move around in big chunks. There is no substitute for ^U^U^N or ^U^U^F, there really isn't. In this day and age everyone has a work station on his or her desk, so the machine can keep up with people holding down the arrow keys. Whatever.
