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.

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.
