Comment 3 for bug 307906

Any application can respond to however it likes to Shift+F10 - just like CTRL+C and other similar shortcuts. The application that has focus will respond to however it is programmed to use that shortcut - it is not a global keybinding. If you launch an application from gnome-terminal, give the application focus and then press Shift+F10, then the application can do whatever it wants with that shortcut, and is not limited by ant other application.
