Full screen mode stopped working, now windowed

I was recently doing some tinkering with PHT (1.3.2) on my Ubuntu 14.04 under Unity. It always used to load in full screen mode every time I fired it up with no problems. Today, while tinkering with some audio settings to force it to use the video card directly at some point it started coming up in a windowed mode where the top bar and the launcher on the left side would not go away. I can force the launcher to auto-hide, but even when maximizing the window it refuses to grab that left side bar. I have no idea why this is happening or how to fix it. Spent quite a bit of time researching this and have come up with nothing.

 

What in the world has changed here?

Had anyone else run into this problem a found a solution?

I just want to get PHT back to the way it was as a FULL screen application.

Never mind, found the solution.

While tinkering I somehow managed to mash the backslash (\) key. In PHT this is a toggle between windowed and full-screen mode.

Jeebus. Can't believe it took me that long to find it. Hoping others don't stumble upon this and waste time, so hope this post helps.
