Frequently asked questions:

• How do I enter the passcode?

  Tap the numbers in the passcode popup in ascending order.

• Why do the keys not move in the page editor?

  You need to long press a key before you can start drag-and-drop. As soon as the key pops out a little, you can start moving it.

• How do I add images to empty keys?

  First, edit-mode must be enabled (tap the pen icon to enter the passcode). Then, double tap a key to open the key editor. Select "custom image" and pick an image from Photos or take a new one using the camera.
