Alt+F4.

Should work in all cases without any programming effort, and it's the best not to disable it.
You already have the Answer on programmatic Close by Rob, see also my comments to his Answer.

Any problems?

Solution 1

You can close a form with err... Close(). You can probably add a key press event to check for the key and stick the close in there. What key do you want to close the form? That may not work if you have child controls focused, in which case you need to hook the (presuming this is WinForms and not WPF) underlying WNDPROC - which I think is on PreProcessControlMessage.

Of course, you shouldn't do this as you're going away from the Windows design guidelines and creating an application which doesn't behave in the way people are used to.

Yep, agreed. Design guidelines are so important, standard stuff like closing windows should be instantly familiar to the user. Click a 'Close' button on your form or click the 'Close' window command in the non-client area. Shouldn't really mess with that behaviour.

Rob, it is easier. You just need to add handler to KeyPress on appropriate control(s). You can also add a button or even a menu ("Exit") -- by default they all can be navigated via keyboard, that satisfies keyboard-only requirement.

But yes, PreProcessControlMessage help to preview event in form, so it will work if children do not add proper handlers...
