How to keep toolbar from auto hiding

I was working on a project and my son came up and pushed something on the keyboard, now my File Edit Arrange etc... is on auto hide.. How do I get it back to display normal again?? Any help is appreciated..

Thank you in advance..

Never mind, finally figured it out, had to click Window menu and uncheck fullscreen option.

You're apparently in 'full screen' mode. With NumLock on, you can toggle the condition with each tap of the '8' key.
