Hi,
does anyone know of a way to disable the Ctrl-D key when running on a
Unix system, or even better set it to what it does in Emacs (delete a
character in command line)? I like the way the emacs control
characters (C-a, C-e, C-k) are available for editing the command line,
but this similarity lulls me into using C-d as well sometimes. Then
my session is gone instantly. Highly annoying.

Hmm...interesting. Not that I've ever written a language interpreter,
but it doesn't seem like it would be hard to have a routine that allows
you to reset the behavior of the command keys like Ctrl-D. Or you could
just use a system variable that gets examined every time Ctrl-D is hit,
with possible meanings (quit session, delete key, do nothing). Then you
could just set this variable in your idl.startup file and everyone would
be happy.
Anyway, thanks for the info,
Mark

Well, it is only a feature on the Unix versions of IDL. On the VMS
version,
CRTRL-D moves back one character instead (LEFT ARROW behaviour).
On my system CTRL-D doesn't kick you out of IDL in the middle of the
command line, only if there is nothing after the IDL prompt
(in the manual it says it does EOF if empty or EOL if not).
It does seem a bit user-unfriendly to me (but I guess that's
juts Unix :)

With that line of thinking it's simple-- stop using IDL.

I'm all for added features such as the one you suggest, but
I am very against taking thinks away willy-nilly. Just ask
those who are still looking for /smooth in contour!

I strongly disagree - I've been using emacs for 12 years, so that beats
the
1 year I've been using IDL, so that's a longer standing feature. RSI may
certainly keep the status quo as the default, but I would dearly love to
see DEFINE_KEY operate on control keys as well as function keys. Ctrl-D
and
ctrl-X would swap definitions immediately!

Since few other programs use ctrl-D to exit, I definitely don't expect
it and
would just like to see it redefineable. Heck, even Netscape (which I'm
using
right now) knows how to do something sensible with ctrl-D.
