For now, some notes about the development of a "meta key" concept. Roughly in chronological order.
- "Meta Hand" on the TX-2 keyboards. Typed to enter a "meta command", or special directions to the assembly program.
- META on the LINC keyboard. Typed as a prefix for commands, much like the TX-2 key.
- ITS and its preceding PDP-6 software uses Teletype model 33 Altmode key as a command prefix.
- EDIT on the IMSSS custom Datamedia keyboard for use with TVEdit. Typed to enter editor commands.
- META modifier on the SAIL keyboard.
- META modifier on the Knight keyboard; used with EMACS as an alternative to the Altmode prefix. Also TOP.
- META modifier on the Kulp "space-cadet" keyboard. Also TOP, GREEK, SUPER, HYPER.
- Stanford SUN workstation proposal from 1980 mentions a META key.
- Sun-2 keyboard has modifiers LEFT and RIGHT. Subsequent Sun keyboards have the diamond symbol.
- The X Window System protocol has five "mod" bucky bits, of which the first is usually mapped to Meta and/or Alt.
