URGENT MAC PROBLEM. NEED HELP - I'm locked out of my macbook.

I am currently at the log in screen and think I pressed a button to trigger symbol change. How do I change it back to letter format?

caps lock, Fn lock....

And creating multiple posts does not make things better.

Restart the Mac (Keep your finger on power key for 15 seconds )
