Petr:

It is not as simple as you make it sound.
Consider the example Timoth=E9e already mentioned.
You have an old x11 plot window open, but the current terminal
is something else.  Maybe wxt, maybe postscript, ... whatever.

In this state, keystroke events in the old x11 plot window will not be=20
delivered to the core gnuplot routines, and so they cannot be handled
by the normal "bind" mechanism.  We work around this by
having gnuplot_x11 handle 'q' locally, but this requires treating it
as a special case.  If we move the 'q' response into the normal
event_keypress() code in mouse.c, it will no longer be possible to
close plot windows opened by a previous terminal type.

In other words, the problem is not lack of a term->xxxx() mechanism.
The problem is in receiving the keystroke event notification.
