“I was reading through this 50-page chapter we’d been assigned, and I was definitely on the verge of dropping the class,” recounted student Lucas Lambert. “My whole perspective changed once I saw that mercifully tiny font.”

“The footnote just went on and on, like an unstoppable river that I thankfully did not have to traverse,” Lambert reported. “I couldn’t believe there was so much to say about the history of arrow keys, and there was no way I was going to read to find out more.”

At press time, the chapter delivered Lambert another blessing by ending at the top of a page.
