XYplorer Beta Club

I'm a new user/licensee and very new to XY explorer.
I am trying to figure out how to add an "Invert Selection" button to the toolbar.
I have added a button to the toolbar but the scripting is beyond me at the moment.
I would really appreciate any guidance.

That's all for the script part...

Well, that was so easy!!!
Guess I've got a lot to learn about scripting...
Thanks,
