TinyMCE - how to add a keyboard listener?

[bjorn]

Dear GWT-users,

we have a TinyMCE widget created according to these postings by mainly
Tom Davies and Aaron:

http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/4d8cd3ba10ae4848

Now, I would very much like to add a keyboard listener to it (get some
onKeyXxx events). Has anyone done this or have any suggestions?

Thanks, Björn
