how to change note input system B vs H

Thanks again. I found out about what Edit > Clef > Reset Position does, but it seems to be intertwined with Edit > Reset Position, which is not the same command, right? In the shortcut editor there are just two "Reset Position"s, and if I change one, the other will change as well (by the way, I have also twice Double Whole Note (or maybe another long note - I’m not by the computer right now).
It seems that I can’t successfully assign a key command for Disable Mouse Input, either. I don’t really care, but you might want to know.
On the other hand, I would LOVE to have a key command for triplet (what the button on the left panel does). Is there any hope for that in a foreseeable future?
The forthcoming update sounds more and more interesting. We can hardly wait!
