I hope that I answered questions you actually asked.

With bigger documents I divide page in two and read it that way. Zoom in or zoom out the document and select thickness of the eraser to make deletion as accurate as possible. Eraser tool allows you to remove unwanted text, shadows or background. To further clean up your PDF, use the ScanWritr’s eraser tool. Now you can choose one of presets or make your own. Clean up unwanted elements from your PDF document. You will see couple of options: how to divide page and order of showing divisions. When you add 'article mode' to quick bar - you can go back to viewing document and press 'article mode' button. Just press long on available buttons to see their names. Click on the highlighter, a box will appear around the text, then press the 'Delete' key on your keyboard to remove it directly. It might be good occasion to check out options. Once your file is open, go to the 'Comment' tab and select the content you've already added highlights. If you want to see part of fixed page then go to quick settings bar, push three dots at the end of bar, go to 'customize quick bar', find 'article mode' button and add it to a bar. I personally don't use swipe and press side of screen instead. You can disable touch and change pages using quick bar menu (arrows). Just choose eraser from submenu and use it on highlighted text. Open quick bar menu and there should be pen option.
