[Terr_]

Starseige: Tribes and Counter-Strike: Sometimes a short thing while the character is coasting through the air.

Tribes in particular also had a voice-tree, and while it was shorter than prose it still encouraged a certain degree of touch-typing.

For example, typing VSAF (mnemonically [start][self][attack][flag]) led to text and prerecorded audio for "I will attack the enemy flag." Little of it survives now beyond references like VGZ for "Shazbot!"
