There are few ways to do it:
1. When Paint or Wet Paint tool is active, just long press Eraser icon in the top toolbar.
2. If you have Magic Keyboard, keep the top-right key (tilda) pressed.
3. Open tool settings panel and change blending to Clear. You can also add this action to the top toolbar or Quick Menu for quicker access.

ahh I see!

how about making the manual into a webpage instead of pdf?
Would that reduce the required server bandwith?

Please update to version 4.1.2
