no no no -- i know *how* he got that literal ^V into the file, what i want to know is *why* he put it there, since i created the same map! entry without that leading literal ^V. i don't understand its purpose. when you edit tom's .exrc, you see: map! ^V^OA ^V^[ka when you edit mine, you see: map! ^OA ^ka which seems to work fine. although there is no ^V in my version of the map! entry, i typed one just to quote the next character -- in this case, an arrow key. what tom must have done was to press three ^V's -- the first two to get a literal ^V in the file, the third to quote the next character. i'm still baffled about why he has that literal ^V *in* the file, since it does not appear to be necessary. rday _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
