Bug 368097 has a test for generic textboxes which can be used as a basis for this.

Needs window to be focused to work properly. Used the DOMWindowUtils.send(Mouse/Key)Event functions here, but these calls should be put somewhere else.

sayrer, where should I add the event functions, or are there already some calls that use the DOMWindowUtils events simulation?

It has sendKey and things that predate your DOMWindowUtils code. I'm not sure if we should replace that stuff with your new method or just add to it. You and bz (who wrote the original EventUtils.js) can make a more informed decision than I can.

Yeah, I think the existing EventUtils key-sending code does what you want here (and also handles people cancelling part of the keypress, etc).
