- You use a two-button mouse to right-click. For whatever reason, control-clicking doesn't work.
- The program you are right-clicking into is Cocoa. That means that this won't work with Finder or iTunes. But it will work with Safari, Mail, Preview, etc. It doesn't seem to matter what kind of program you are clicking from, only what kind you want a menu in.
- This seems to work regardless of whether you have an Apple or third-party two-button mouse, and it works in 10.5 and at least 10.4.11.
I'm not sure why this doesn't work with Carbon apps, or why it requires a literal right-click, but if you find yourself switching back and forth between applications, see if you can't do what you need in one of them by right-clicking from the other.
