I have a web browser object, set to editable, in a form. Now I want to use that object as a text entry (with, in the end, syntax coloring) and I've found Yousfi's article most helpful.

But, but... the code in the implementation has no parameters! It reacts to _onkeydown() but I don't know which key, because there's nothing holding the value. I see he tried to resolve that by using GetAsyncKeyState API call, but he has to call it 255 times to find which key was last pressed - and not to mention anything about ctrl or alt... so is there a better interface to implement? Or a way to get to the event object from DOM - it's surely passed to the event inside the document, but not to the interface.
