enum

Phosphor::Key

Inherits Enum < Comparable < Value < Object

Named keys produced by terminal input.

Key is the discriminant stored in every KeyEvent. Widgets pattern-match on this enum to translate keypresses into application Msg values. Key::A..Key::Z match lowercase letters only; an uppercase letter produces KeyChar instead, so shift state is recoverable by checking whether the key is a Key or a KeyChar.
