Hi;
We recently moved to IDL 5.5, running on a Dell Inspiron laptop under Linux
8.0, with an NVidia Gforce 4 card. Everything works really well except for
one irritating bug - IDL doesn't recognize the arrow keys. No other program
I run has that problem, so I assume it is either an issue with IDL or the
way I have it set up. Any thoughts out there about how to fix this problem?
TIA,
Chris

Thanks for the several offers of help. Though they didn't fix it directly,
it did lead to a partial solution - the problem only occurs in a
gnome-terminal window, not an xterm. So I can work from there.
Thanks again
Chris

Try using HELP,/ALL_KEYS to see what IDL thinks your keyboard mapping
should be. On my system I have these settings for the arrow keys:
LEFT ARROW (\033[D) <Cursor Left>
RIGHT ARROW (\033[C) <Cursor Right>
UP ARROW (\033[A) <Previous Line>
DOWN ARROW (\033[B) <Next Line>
You can experiment with key mappings using DEFINE_KEY. Check the
documentation for the exact synax, but it would be something like
DEFINE_KEY,'LEFT ARROW',ESC='SomeEscapeSequence',/BACK_CHARACTER
DEFINE_KEY,'RIGHT ARROW',ESC='SomeEscapeSequence',/FORWARD_CHARACTER
DEFINE_KEY,'UP ARROW',ESC='SomeEscapeSequence',/PREVIOUS_LINE
DEFINE_KEY,'DOWN ARROW',ESC='SomeEscapeSequence',/NEXT_LINE
If you figure it out, just put the commands in your .idl_startup file.
