How to capture control or alt + key on Windows

Trying to capture a control + 1 or Alt + 1 on windows in the keydown event, but it never seems to fire.
The window does NOT have a menu bar assigned.

Any idea if this is possible?

You can use the KeyUp event on the window http://documentation.xojo.com/api/deprecated/window.html#window-keyup to handle the key press and http://documentation.xojo.com/api/hardware/keyboard.html one of the properties of the Keyboard module to determine if the control or alt keys were pressed.

Well that was unexpected. I assumed you had to return try on the key down to get the key up event
