What the Pen Tool Does

The Pen Tool in Scroll lets you draw, handwrite, or annotate directly on ebook pages. It’s great for circling, underlining, sketching diagrams, or adding free-form notes by hand. Teachers can review your pen-annotations, and you can return to them later.

Steps to Use the Pen Tool

1. Open the Pen Tool
   • Select the Pen Tool icon to open the pen annotation popup.
2. Select Color
   • Choose the pen color from the palette of available options.
3. Adjust Thickness
   • Use the thickness control to select how thick or thin you want the pen strokes to be.
4. Eraser
   • Use the eraser to remove pen marks. You can erase individual strokes or parts.
5. Undo
   • Mistake? Use the Undo button to revert the last pen action.
6. Clear All
    
7. Save Your Annotations
   • After you finish writing or drawing, make sure to Save so your pen annotations are stored and can be viewed later.

Tips & Best Practices

• Use light pen colors if the underlying text / images are dark, so your annotations remain visible.
• Thinner strokes are often better for text-dense pages; thicker strokes help with diagrams or sketches.
• When erasing, make sure you’re selecting the correct stroke; sometimes parts of your annotation might overlap.
• Use Undo instead of Clear All if you only want to fix one mark.
• Save often—especially after making lots of annotations—so you don’t lose work.
   

Troubleshooting

• If the Pen Tool icon isn’t visible, the ebook might have pen-annotations disabled (publisher settings).
• Sometimes pen strokes lag or don’t appear instantly; ensure the page is fully loaded.
• If annotations don’t save properly, check your internet connection or whether you’re logged in correctly.
• If your device has limited touch precision (small screen or low resolution), zoom in before annotating for better control.
