Look to the right. See that gray bar that ends in arrows? That's
your scrollbar! Click on the arrows to see the text that doesn't
fit in your window. Click on the bar itself to move through the
document at breakneck speeds. Or click and drag the placer box to
the exact location you want to visit. Don't see a scrollbar? Then
resize the window until it's small enough to necessitate a scroll
bar. See? Now scroll away.
