Or, you could always get version 4.12 of JOVE (cs.rochester.edu has it
available for anon ftp) which has a new set of functions that allow creation
of key-maps, which can be bound to any key.  Thus, you create a keymap, bind
it to ^[[, and then bind functions and/or macros to the characters in that
keymap; ie bind-to-key next-line ^[[B.  Remember, though, JOVE puts ansi
type terminals in application mode, so that the numeric keyboard can be used
for functions if you wish.  Versions 4.9 and earlier only supported the
arrow keys (bind-to-key ansi-codes ^[O was needed to activate this); with
user defineable keymaps.  Now, you need to bind you keymap to (for ansi
terms) ^[[ and ^[O and then bind previous-line, next-line, forward-char &
backward-char to both \^\[\[[A-D] and \^\[O[A-D] (using regular
expressions). Then bind the functions you want the numeric keypad to produce
to ^[O*, where * is the letter corresponding to that key, such as m for
ENTER.  Oh, and the functions you bind to the PF keys should also be bound
to both ^[[* and ^[O*.
