Get rid of fit in window view?

So I clicked ‘fit in window’ in the view tab, and can’t figure out how to get it back so I can use the gain/panning on the tracks. I tried the ‘zoom normal’ and that didn’t work, either. Any ideas?

Click on the bottom edge of a track and drag it down to make the track taller.
Tip: When working with a lot of tracks it is often easier to use “collapse all tracks” (View menu) rather than “fit vertically”, then you can click on the button at the bottom of the track information box to expand the track back to normal size.
