Instead, if you want to remember the thought you were about to highlight or underline, write it out long hand, and from short term memory not copying rote, in a note book.

This exercises the full path: reading, comprehension, decision you’ll need to recall, storage, retrieval, and output from mental storage back into physical world.

Plus, the notebook then provides a hook for refreshing the information geography in your storage. Reskim the notes and you refresh the larger narrative and how it hangs together. Revisit the notebook on a periodically decreasing interval, you’ll still recall the narrative decades later.
