Capturing an specific key pressed for ALL events

Greetings!

I would like to know if a key, say, Keys.ESCAPE, is pressed no matter which event or location is live. I know I can set it on each event for each object, but is there a way to capture this for all events?

thanks,

jose

If all you want to do is have a default action for the Escape key on your Form, you might simply want to use Form.cancelButton, which gets its click event fired if the user presses Escape on a control that does not accept the Escape key.

If you do want to receive all key events, you can use a message filter via Application.addMessageFilter. Note that Form`s add message filters, and they're first-come first-served, so if you want to preempt Form's filter, add one ahead of time. See IMessageFilter and preFilterMessage.
