i'll throw in blender into this discussion.
I haven't used it for ages but I've used it a few times and found there is a hidden menu that you access by dragging some bar that doesn't look draggable.
and it's a useful menu too... why hide UI and not give indication that it exists?
that's a "Ch" pronounced as a "K"
