This attribute allows the system to control hand movements.
Substructure of the attribute:
(<top-state> ^motor-link-hand <ml>) (<ml> ^flip-page << forward backward >> ^distance << 1 2 >>)If the ^flip-page attribute is not present, the rest of the processing is ignored. If it is present, the distance is evaluated, and then the OMI is flipped that number of pages. This results in the scheduling of a resource limitation for motor-link-hand (see ^resource-in-use).
Implementation of output function: MoveHand in motor.c (this then invokes OMI simulation functions in OMIsim.c).
