What's missing in 'hacks' like these is the core purpose of note taking in learning contexts: to increase retention and understanding through mentally summarizing and connecting ideas. You do this first when encountering a subject, then later through active recall, repetition, and practice. It's very difficult to do that with bare bones notes and underlined keywords/phrases. It skips over the necessary mental processes involved in moving information from short to long-term memory, and for understanding. Highlighting keywords/phrases doesn't aid in retention or understanding, it avoids it.
