Well the right click is, and has always been, built for the Context Menu, if you're looking for info on how to edit and customize the context menu check out the livedocs here
macs don't have the same right-click capability as pcs
Uhh, just because the mighty mouse (the default mac mouse) doesn't come with a right click button, doesn't mean you can't right click on a mac. Macs have the same right-click capabilities as PC's do. You can purchase regular mice for Macs or control+click to get the same effect.
hmm, I'm not 100% positive but I don't think you can completely disable the context menu and make the right-click a function. Otherwise we would see it a lot more often.

You're generally correct, though there are a few ways to cheat. The first is to make an AIR application -- but that's not really an option if you're making a game that's going to be played in a web page.
The other way to cheat involves sticking Javascript in the page that intercepts right-clicks before they get to the Flash app. It then passes the coordinates to the app via a separate means, so as far as the Flash player is concerned, there's no right-click. That works if you can control the page that the app is embedded in, but it wouldn't work for something being distributed across the web normally. If you're interested in the details, you'll have to google them -- I came across the technique once, but I didn't bother bookmarking the page.
