35 * 1. extend it to the wm_command and wm_syscommand notifications
36 * 2. add some more tests with special cases like dead keys or right (alt) key
37 * 3. there is some adapted code from input.c in here. Should really
38 * make that code exactly the same.
39 * 4. resolve the win9x case when there is a need or the testing frame work
41 * 5. The test app creates a window, the user should not take the focus
42 * away during its short existence. I could do something to prevent that
