@Chaz9999: There is no general answer to your question, as the distance between baselines in the text layer is not fixed but can vary due to smaller/larger font size, subscript and superscript, etc.
What I do with LectureNotes is:
- enable GMD Gesture Control, Hide Status bar command
- Use spen button button for eraser
- pen toolbox enabled for easy color change
These 3 for me are the essentials
My spen button isn't working, when click it, nothing happens. Do I have to enable it somehow?
