So, I had my spreadsheet open and I dropped something on the keyboard and it now shows a chart that I can't get out of. There are no menu options across the top. I toggled between Full Screen (CTRL+SHIFT+F1) which doesn't really change anything other than status bar at the bottom. Unfortunately, I have the spreadsheet auto-saved on OneDrive so I can't revert back. Attached is what I see. Any suggestions?
