This is probably a really dumb question, but I seem to have lost part of the user interface…! In the attached pic, I’ve added a red arrow pointing to the lower left. The three-button menu is missing and I can’t seem to find a way to bring it back. I must have fat-fingered something and before I realized what I did, POOF gone. It’s probably a shift-something or a ctrl-something, but I just can’t seem to find what.
