I am supporting a user that can't type and consequently often hits AltGr (on the right side of space-key). He has enough power to decide he wants to disable that key (instead of learning to type). and he asked me to quickly get rid of that key
The only way I found was using KbdEdit and map AltGr to "KANA" (How to) but unfortunately that does not behave as promised. I am waiting for support from the developer, but thought that meanwhile I should see if anyone of you has better suggestion how to address this.
