Well, really any move is a jump to a new location.  In the case of Rev's
move command, a move is based on several factors: moveSpeed, duration, and
overall distance.  The host computer's processing power, and the power of
the graphics card, and monitor refresh can also be issues.  You'll need to
find a balance between the size of the jump and speed at which the jumps
take place.
