They are defined by the application. In other words, they have no local
function, and they don't modify other keys by default. The VT420
supports Key Position Mode, in which keys send ISO 9995 key position
codes (A01, C99, etc.) instead of ASCII/ISO Latin-1 codes. In this mode,
the "modifier" keys, Ctrl, both Shifts and both Alts, send status codes
for key up and key down events.
