No problem. I'm still wondering though as to why CTRL-left/right/up/down
cause sbcl/linedit to hang? Sorry, i'm only a humble beginner to common
lisp so all i can do is report problems :|

I've attempted to change the key mappings to use home/end keys for
bol/eol but came stuck... i know that the keycodes generated for
home/end etc are a two-code thing, but not sure how to specify it in the
keys file within linedit - the defcommand using "home" and "end"
seems to be ignored by these keys which get caught (on my system
atleast) by the defcommand for "M-O" (IIRC) and the 2nd part of their
keycodes comes out as 'F' or 'H' (IIRC) at the prompt.



Cheers,
james.
