How-to Guide
1. Start Brush and adjust settings
Entry point: Tools → Brush → Use Finger
- Open the document you want to mark up.
- Tap Tools at the bottom.
- Tap Brush.
- Turn on Use Finger.
- Choose the brush settings you need, including the standard pen, highlighter, or eraser.
- Select a brush color.
- Drag the thickness slider to adjust line thickness.
- Write or draw directly on the document page.
Success Criteria
- UI state: the Brush panel is open, and pen type, color, and thickness settings are visible.
- Next actions: when you move your finger on the document page, matching marks appear.
Tips While Using
- Common mistakes: if Use Finger is not turned on, the page may still respond mainly as normal touch navigation.
- Environment limits: on a smaller screen, adjusting the page zoom before marking up can make writing easier.
2. Disable Brush
Entry point: Tools → Brush → Disable Brush
- Open the document page where Brush is currently in use.
- Tap Tools at the bottom.
- Tap Brush.
- Turn on Disable Brush.
- Return to the document page and confirm that drawing has stopped.
Success Criteria
- UI state: Brush stops working, and touch actions no longer create new strokes on the page.
- Next actions: you can continue browsing the document with fewer accidental marks.
Tips While Using
- Common mistakes: if Brush is not disabled after markup is finished, extra strokes may appear while you continue moving through the page.
