Key input and event listeners

I have a pretty effective punch&roll extension for Audition functioning now - it works well and does some neat stuff.

Apart from the packaging issues I'm having for distribution though, I have one other thing I'm trying to do.

For voice recording, it's important to be able to activate this with a keypress - not just mouse input via buttons.
At present, it looks like all key events are prevented from reaching the panel for my extension.

My questions are -

1) Is there a way to get key input of any kind?

2) if not, I see things like UIControlEvents - but there's basically zero documentation on this. No idea what events might be available or how to listen for them. If I CAN get UIControlEvents with useful data then I can bind hotkeys to some other Audition functionality which I can then react to, thereby using them as 'key events'.

I know that #2 can theoretically work if there are useful events - I watched the transport loop start/stop events to try it out in theory, and that works fine. Unfortunately i can't use that event, because it has adverse side effects in the recording rocess.

Any help much appreciated. A lot of voice actors will thank you.
