Apple Motion 4 - Manual (Page 466)

Start Offset: A slider that lets you delay the beginning of the behavior’s effect relative
to the first frame of its position in the Timeline. Adjust this parameter to make the behavior
start later. The units of this parameter are in frames.
End Offset: A slider that lets you offset the end of the behavior’s effect relative to the
last frame of its position in the Timeline, in frames. Adjust this parameter to make the
behavior stop before the actual end of the behavior in the Timeline. Using this slider to
stop the effect, instead of trimming the end of the behavior in the Timeline, freezes the
end of the effect for the remaining duration of the object. Trimming the end of the
behavior resets the object to its original parameter.
Apply To: The Apply To (Go) pop-up menu shows the parameter being affected and can
be used to reassign the behavior to another parameter.
HUD Controls
The HUD lets you set the start and end values and change the parameter assignment.

Link
The Link parameter behavior forces the value of one parameter to match that of another
“linked” parameter. The source behavior can be within the same object or from another
object. The linked parameters must contain numerical data. Parameters controlled by
checkboxes, menus, and other non-numeric values cannot be linked. The linked parameters
also must contain the same number of attributes. You cannot link a compound parameter
such as Scale X-Y-Z to a parameter such as Opacity which has only one slider. You can
however, link a compound parameter such as Scale X-Y-Z to Position X-Y-Z.
