Fun fact: Origin of "upper-case" and "lower-case"

UPPER-CASE and lower-case

These terms originated from the common layouts of the shallow drawers called type cases used to hold the movable type for letterpress printing. Traditionally, the capital letters were stored in a separate shallow tray or "case" that was located above the case that held the small letters.
