Unfortunately keyboard control in full screen is very limited.

From Adobe documentation:

Currently, Adobe Flash Player does not allow keyboard input when displaying content in full-screen mode. Flash Player 10 changes this, allowing for a limited number of keys to be usable in full-screen mode. These include Tab, the Space bar, and the (up, down, left, right) arrow keys.

This change affects all SWF files played in Flash Player 10 or later. This includes SWF files published for earlier versions of Flash, so long as they are played within Flash Player 10. This also affects non-app content in AIR.

Note: App content in AIR can set the value of stage.displayState to StageDisplayState.FULL_SCREEN_INTERACTIVE for full keyboard support in full-screen mode.
