a coupple of keystroke shortcuts??

Looks like the thread veered from original point.
Back to the idea of a 0 Palette or perhaps this:

Grab a light (or layer set), set it's position, focus, zoom, scale, x pos, y pos, z rot, keystone [n], or shutter [n] into palette windows and have a right click option that will use these values to update the "Edit Fixture" page for offsets.

The same would also work for defining all parameters and then having a right click assignment for setting default values.

I'm saying make it work like Highlight and LowLight.

(It's only a nightmare for the code writers)
