While you’re annotating, forScore displays a toolbar so you can change drawing presets, tools, save or cancel your changes, or move between pages. This toolbar covers up part of the page, so you’ll need to move it when you want to annotate near the top of the screen.
On either side of the toolbar you’ll see a set of three horizontal lines. This is a standard iOS control that signifies when something can be moved up or down, for instance when reordering items in a list. Tap and drag this control up or down to move the annotation controls out of the way and they’ll stay there until you move them again (even if you exit and re-enter annotation mode later).
