You can't find it because it is not there. IDL is using
different calls to OS-specific functionality in the
dialogs, and that is not exposed to us using widgets.
In Windows 7, anyway, when you set the INPUT_FOCUS to a
button, the button gains a thin, almost unnoticable,
dashed line just inside the button boundary that will
distinguish it from other buttons. (I had to look twice
to find it!) AFAIK, there is no way to change the action
from the space bar to anything else.
Cheers,
David
