Bars on display - how to remove

I did a keystroke and a band shows across the middle of my Audacity display. Any idea what keystroke caused this, what it is, and how to remove it?
I’m using version 2.3.3.

You may have pressed the “F6” key. Press “F1” to get back to normal.

That did it! Thank you!!!
