I would try an activation trigger in the listbox, using <widget> cget to
obtain a value for stuffing into the listbox. The keywords are far from
the tip of my mind; try reading the listbox manpage for something less
vague.

With suitable dextrous appendment of spaces, I guess so. Have you looked
into Tix or any of the other Tk toolkits?

I guess that a y movement function is needed for each listbox that
updates not only the other listbox but also the scrollbar, like the
function you wrote for the scrollbar to update both listboxes.

This question really belongs on a TCL/Tk list somewhere, rather than on
the list for a widget placement tool like vtcl.
