Pressing a number (or letter for numbers above 9, see scripts) will play from the current playhead to the number
pressed. Clicking a number prior to the current playhead will rewind to that point. Hitting the "n" key will go
to the next stop point. "b" will go to the prior.
Pressing the "s" key will show the currently selected number in the top right corner. Hitting "s" again will hide
the number display
