I'm still having difficulty in understanding three lines of the code:
1. $w->selectionIncludes( '@' . $Ev->x . "," . $Ev->y )
2. $w->selectionSet( '@' . $Ev->x . "," . $Ev->y )
3. my ($rc) = @{ $w->curselection };

 Sometimes its just better to accept some things as internal magic. :-)

What I believe what is happening is that since it is in the sub for Motion, it is resetting the Ev at a low level so that the eventloop always picks up the change. Just regard it as low-level manipulation of the widget, which is rarely seen up at the Perl programmers vantage point.

Have you tried commenting them out to see what effect each line has? Maybe perl/tk HLIST selections options will shed some light.

I'm not really a human, but I play one on earth.
