Control Context Menu with KeyBoard?

I have augmented the code of my flash context menu similar to the Kirupa banner (disabling default options, and placing a custom option in the menu etc.)

I am wondering if anybody has any ideas or has been able to control the context menu with keystrokes (for example: once right-clicked, close using any key on the keyboard).

I have observed that any option in the context menu can be escaped with the respective alpha key it begins with (ie: if your menu starts is “Hello” you can close it with ‘H’). The problem in this method obviously being you would have to create a custom menu item for every letter in order to quickly escape it on a key stroke… (not to mention a massive context menu)

Any ideas are greatly appreciated…
