A Motor Macro is a pre-programmed series of muscular movements, programmed into a Headcomputer for execution on command. A Macro's scope can be limited to a part of the body, or may control the entire thing. They can be triggered through various means (vocal, subvocal, gesture, etc.).
Motor Macros are subdivided into Gross and Fine types, affecting different sets of motor skills.
Motor Macros can be used maliciously, as in the case of the Seagal Virus, which caused hundreds of infected headcomputers to cause their hosts to spontaneously break their own necks.
