Ok, I think I am picking this stuff up now.

Does anyone know the syntax to force a mouse to be restricted to an area on a window? This would be incredibly useful to me, for the following reason: I would not accidentally close the right-click menu by moving my mouse off of it. I noticed that [escape] button closes the menu, so it would work similar to Autocad.

Basically the right-click menu is a special class of window. How do I restrict mouse position to the area inside a window?
