* 1. extend it to the wm_command and wm_syscommand notifications
* 2. add some more tests with special cases like dead keys or right (alt) key
* 3. there is some adapted code from input.c in here. Should really
* make that code exactly the same.
* 4. resolve the win9x case when there is a need or the testing frame work

* 5. The test app creates a window, the user should not take the focus
* away during its short existence. I could do something to prevent that
