Fix shortcut (Esc) handling in test/keyboard.cxx

Browse Source 
Esc is intentionally consumed by the test program (see comment) but
other keystrokes (shortcuts) must pass to allow zooming with ctrl/+/-/0.
The old code filtered all shortcuts which turned out to be wrong.

Not being able to zoom was caused by a previous commit that lowered
the priority of the zoom key handler - which alone was not wrong.
