Reading Arrow keys from keyboard ? [message #706]

We would like to use the arrow keys from our vt240 keyboard
(at least I think it is a vt240). In IDL we can use GET_KBRD()
to get ASCII keys but have not figured out how to determine if
an arrow key was hit.
for example
IDL>a=get_kbrd(1)
IDL>[D
->this is what happens if we hit the left-arrow key (its code is
ESC-[D I beleive).

If someone knows how to do this please respond via e-mail to
zhang@bnlx1l.nsls.bnl.gov (or bnlx1l::zhang )

Thanks!

(ps it should also apply to function keys as well?)
