    Glitch attaches to the player automatically.

    Step 5

    Optional: combine with 1.75× pitch-locked speed

    Stack silence skipping with pitch-corrected speed to halve effective runtime.

    Drop bookmarks where it matters

    When the prof finally explains the proof, hit the bookmark key. The note travels with the lecture.
