=item NAME
A key dump example
=item FEATURES
Tests the correct implementation of keyboard event subsystem.
The following features are tested:
- Direct flow of keyboard event
- Correspondence of a syntetic key name to the real name
- key_event() functionality
- Key event propagation. Not that if it is disabled ( a clear_event() is called )
no system-bound event ( like menus etc. ) are expected to be initiated.
- Diaglyphs type ( f.ex. dieresis + 'e' )
- Alternative keyboard layout ( a Euro sign )
