Spreadsheet stuck on Chart

[Creeperkat]

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?

It looks like you have hit the F11 key which creates a chart tab in excel!
Not to worry, if you see the worksheet tab names along the bottom you can right click it and select the Delete option.
If you do not see the worksheet tab names along the bottom you can use CTRL+PAGE UP  and/or  CTRL+PAGE DOWN to switch worksheets.
Switch to a worksheet where you see the black FULL SCREEN button at the top of the sheet, and when you click that it will reveal the Worksheet tabs along the bottom.  From there you can right click it and delete it.

Let me know if you have any trouble!

PHEW!  The CTRL+PAGE UP worked and I closed all the Chart Tabs. All good now!   Thank you Scott!
