Parameter List
Any keyframeable parameters of your selected items can be displayed in the list on the
left side of the Keyframe Editor tab. This includes object properties, filters, and behaviors.
By selecting multiple items in the Layers tab or Timeline, you can compare parameters
across multiple objects.
Activation checkbox: The checkbox on the left determines which parameters are displayed
in the graph. Checked parameters are considered “active.”
Parameter name column: The second column lists the object name and the parameter
names for each object.
Value column: The third column displays the parameter value for the frame where the
playhead is currently positioned. If the playhead is parked on a keyframe, the field shows
the value for that keyframe. If the playhead is not parked on a keyframe, the field shows
the value of that parameter at that frame. For more information on changing the values
of keyframes, see
Modifying Keyframes .
You can click the value to activate the field. When Record is enabled, a keyframe is
automatically added if you click the value field at a frame that has no keyframe. To type
a value in the field, double-click it.
Note: Selecting a keyframe does not display the value of that keyframe, it shows the value
for a parameter at the frame where the playhead is currently positioned.
Animation menu: The fourth column contains a pop-up menu that mimics the Animation
menu found in the Inspector. However, the Animation menu in the Keyframe Editor
contains several commands not found in the Inspector.
• Enable/Disable Animation: This command remains unavailable until keyframing is applied
to the parameter, either by using the Record button or by directly adding a keyframe.
Once the parameter has some animation applied, the command is automatically
renamed Disable Animation. Activating it at that point effectively hides the keyframes
you have set, restoring the parameter to its default value. However, the keyframes are
not thrown away. Choosing Enable Animation restores the parameter to its last
keyframed state.
• Reset Parameter: Removes all keyframes and settings for this parameter. The parameter
value is reset to its default value.
