Thanks for the info JD.
C-h k M-tab gives me:
M-TAB runs the command complete-symbol
which is an interactive
compiled Lisp function in `bindings'.
It is bound to M-TAB.
(complete-
symbol ARG)
Perform tags completion on the text around point.
Completes to the set of names listed in the current tags table.
The
string to complete is chosen in the same way as the default
for M-. (
which see).
With a prefix argument, this command does completion
within
the collection of symbols listed in the index of the manual for
the
language you are using.
C-h k Esc Tab gives the same message..'Esc Tab runs the command complete-
symbol'...
After Dick's suggestion I defined M-q for idlwave-complete and that
seems to have worked. Any idea if that will interfere with any other
commands in IDLWAVE or Emacs(I'm very new to this)? Perhaps there's a
better alternative I should get used to. For some reason Tab won't play
nice for me...oh well.
With regards to OS X...it's definitely been fun to tinker with all of
this...unix, xfree86, emacs, etc. is a whole new computing world for me.
I'm sure I'll have lots more questions so I definitely appreciate the
help! My company just happened to still have a couple of Mac licenses
around for IDL that they weren't using anymore so I thought I'd try it
out. I didn't quite realize IDL ran through an X-window environment on
OS X 8-)
I see your email address is from U of A. I assume your in Tucson...nice
rain we've been getting, huh :)
Thanks again!
