Application interface to retrieve a Key.

This method returns one pressed key (as an Key object). If no key has been pressed, the calling application thread is blocked until a key is available – this is achieved by using a Semaphore.

Returns: Pressed key

Todo:: Implement Method

Note: This method is equal to the correspondent method in base class Keyboard, with the only difference that the call will be protected by a Guarded object.
