We’re working on a new Explorer and Properties panel that will be rebuilt from the ground up.
I’m closing this ticket because we won’t fix this in the current version, but instead address it in the new Explorer and Properties panel. Please bear with us, it will be a massive improvement.
A fix for a very similar bug just went live. Although it doesn’t address the F2 shortcut not working, it should fix the context menu “Rename” being greyed out!
