After a bit of research, I decided to ask a question to rule out an option that doesn't look viable. I have seldom used the right mouse button. Now I want to have a menu pop up whenever ANY control is right clicked, or even if the form (no control) is right clicked. This appears to be somewhere between tricky and impossible as 'default' right mouse button behavior. It looks like some controls, perhaps buttons as an example, don't generally deal with right mouse button clicks.
