OK, yes, thanks, that sounds like a possible good solution. I like the idea of subclassing the widget, and then redefining the Paste sub with a minor modification.

I guess I was sort of afraid to look in the TableMatrix.pm file because I didn't think I would understand it. But it looks like TableMatrix.pm is just the default bindings plus some useful interface functions such as Paste. Not too scary afterall. (though I definitely don't "get" everything.)

Also, I sort of assumed if a sub wasn't mentioned in the documentation that it was considered "private" and I wasn't supposed to use it unless I really know what I'm doing. But I guess I could say now that I know that's what I need to do.

(I do think making a subclass is the best way to go (I love OO), but another possible solution it seems, (now that I know there is a Paste sub I can call) would be to just rebind <Control-v> to my own sub and I could do my 'before and after' code with a call to Paste in between. Though I would also need to rebind <ButtonRelease-2>.)

back to your your example: in the Paste() redefine above, you could instead of writing all the original Paste code in between 

print "start paste\n";
my $w = shift;
my $cell = shift || ''; ## Perltk not sure if translated correctly

and print "end paste\n";, you could just call $w::SUPER->Paste($cell); Is that correct? I read a couple of the tutorials on OO with Perl, but I haven't really put it to use yet.

Thanks again so much for the reply. You were very helpful.
