The Highlighter tool is very easy to use in GoodNotes. Select it and draw over any words or objects on the page to highlight them.
Choosing a color and thickness
The Pen, the Highlighter, and the Shape tools each have their own set of shortcuts for colors and thicknesses in the contextual menu (the right-hand side section). Customize a color or thickness slot by tapping it twice.
Configuring the tool
Tap the tool twice to access its settings.
- Draw in Straight Line: If this is enabled, all lines you draw will be straightened automatically.
