Xcode 12 lock object library open not working

Per other posts(for instance: https://developer.apple.com/forums/thread/103777?answerId=332884022#332884022) and my own experience, in previous Xcodes you could lock the library open with the option key. This does not seem to be working on Xcode 12.

BUT - I've remapped my keys and perhaps this is the problem.

Has anyone else found a way to keep the object/media library open on Xcode 12? If you have then I'll have to deal with my key-remapping.

Thank you.
