I've just found if you enter "lock clip" in the Search field when "Global Bindings" is selected from the pull-down, you only see "Lock Clip Position & Data."
But if you select "Track View" from the pull-down and do the same, you see "Lock Clip Position" and "Lock Clip Data" separately, too.
Hmm... misleading, isn't it? Or can clip position and data be locked in other views than TV?
