Panel Keys:New user. When I first downloaded the program, the F5,F6,F7,and F8 keys worked to remove the panels--now they do not. Any suggestions? Thanks!!

They still do, what happens when you press the key?
Additionally the tab key also be utilized.

Nothing happens--no response from the key at all!!
After my last post, I tried a diffeent keyboard and it worked--thanks for your help anyway!

If you're using a Mac laptop, you need to hold down the fn key to make the function keys work.

Other keyboards might also have special keys or a software control panel to activate the function keys; they are often used for manufacturer-specific functions.

F5, 6 7 & 8 keys work for me. Thanks for raising the issue, discovered a new feature by trying this for myself!
