I tried to do this for a friend of mine a couple of years ago. That is, rig the keypad to act a bit like it does in EDT with `gold keys' (I think), and effectively be in insert mode all the time, etc. Much mapping of the tail ends of the escape sequences returned by the keys, etc. It partly worked, but eventually I ran up against vi's "too dangerous to map that" message. I can't find any doco about exactly what causes it, though it seems to be maps which cross insert/command mode boundaries. I'd love to know exactly what causes it. Then I'd have a better idea of how to work around it. - Cameron Simpson -- ACSnet,CSNET: cameron@eecs.unsw.oz JANET: eecs.unsw.oz!cameron@ukc UUCP: ...!uunet!munnari!eecs.unsw.oz!cameron BITNET/ARPA: cameron@eecs.unsw.oz.au
