Function keys on left side enable one small hand to simultaneously strike function key(s) and any
combination of Shift, Alt and/or Ctrl, readily & purely by touch of an experienced user.

Double width backspace key.
Tray-shaped rewriteable area for scribing meanings of function keys or hosting function key templates.
Durable mechanical tactile keyswitches.

Coiled cable.
Stiff cable, difficult to uncoil to 3 meter length.

Other comments
Later OmniKey 102 models moved the ESC key above the location shown.
OmniKey Ultra models moved the ESC key above the location shown and duplicated the function keys in the area
above the top key row where the 102 provides space to write meanings of the function keys.
The Ultra became the pattern for the original
Avant
Stellar when its maker bought the tooling from Northgate.
