To switch to the vertical scrolling display mode, load your song, tap the center of the screen to bring up the song overlay, tap the display mode icon at the bottom (to the left of the page scaling mode icon with blue arrows) then change the default display mode dropdown to "Vertical Scrolling".

You can use a pedal to scroll and you can scroll automatically if desired as mentioned by Geoff. If you want additional information about this, I can provide it.
