Keychron K1 Pro vs K3 Max80% vs 75% Low-Profile

The Keychron K1 Pro uses an 80% layout with 87 keys, including a dedicated navigation cluster with Home, End, PgUp, and PgDn keys that programmers often prefer. The K3 Max has a more compact 75% layout with 84 keys, which may require using function layers for navigation tasks.
