Why not?  Because a lot of terminals have cursor keys that conflict with
vi's keystroke commands.  Take for example one of the Televideo type term-
inals.  The cursor right key sends a ^L and the cursor down sends a ^V.
Vi uses a ^L as a 'redraw screen' command and a ^V as a 'quote next char'
command.  What does vi do in this case?  It preempts the action normally
attached to the keys in favor of the cursor keys, leaving the poor user
without a redraw screen or quote next.  Then there's the ADDS Regent 25
which uses a ^Z as one of it's cursor control keys.  Under 4.2BSD, vi isn't
built to catch that.
