Low threshold values closely match the original

of k eys.
High threshold values produce the fewest keys but
may not match the original animation with much
accuracy.
Note: When Red uce Keys is active, there is
additional calculation time after each completed
recording.
Mouse Input Device rollout
Controls animation using the horizontal or vertical
motion of the mouse. The available settings
include the following:
Hori zontal/Ver tical—Specifies which mouse
motion drives the animation.
Scale—Scales the relative effect of the mouse
movement to the animation response (Spinner
Value: float, 0 to 999,999)
Flip—Flips the direction of the response relative
to the mouse movement. For example, if moving
the mouse horizontally to the r ight produces
a clockwise effect on a Rotation con troller.
Activating Flip w ill reverse the rotation to
counterclockwise.
Keyboard Input Device rollout
Lets you assign most keyboard keys to drive the
animation.
