Appearance & Settings
Tune how documents look and how the viewer behaves. Quick settings are in the toolbar's settings menu; the rest live in the viewer settings.

| Option | Use |

| Custom | Pick any color |
Reading comfort

- Volume-button scroll — page through with the volume buttons (touch and TV).
