[Rd] RAqua line-editor navigation keys

[Peter McMahan]

this is a suggestion for a feature in future releases
of RAqua for mac OS X:
It would be very nice if the gui conformed to the
navigation keys that most other os x apps do (with the
exception of ms word and mozilla).  i am referring to
the use of ctrl- f, b, n, p, e, and a for navigating
forward one character, backwards one character, up one
line, down one line, to the end of a line, and to the
beginning of a line, respectively.  also, ctrl-d to
delete forward would be convenient.
these work in the command-line version from terminal
because they work with everything in terminal.
this is not major, of course, but it would be nice and
would go a long way to make RAqua feel more native to
os x.
thanks,
peter
