Description

The KeyCap identifies the text printed on a physical key on a computer keyboard. This is distinct from any scan code that it may generate (KeyCode), or any symbolic name (KeySym) that might exist for the key.

Processing expectations

Formatted inline. The MoreInfo attribute can help generate a link or query to retrieve additional information.
