•
Value: Parameter values at the playhead position appear in the third column. Modify a
parameter value by dragging left or right over the number in this field. Or double-click
the field, then enter a value. The value displayed and editing options depend on several
factors: If the playhead is parked on a keyframe, this field shows the value for that keyframe;
adjusting the value alters the keyframe. If the playhead is not parked on a keyframe, this
field shows the value of that parameter at the current frame. If the parameter has keyframes,
adjusting the value creates a new keyframe at that frame. (For more information on
changing the values of keyframes, see
Add, delete, and modify keyframes on page 465. For
more information on value sliders, see Value slider on page 128.)
•
Keyframe and Keyframe Navigation buttons: Keyframe controls appear in the fourth column.
These controls are identical to those found in the Inspector: the Previous Keyframe button,
Add/Delete Keyframe button, and Next Keyframe button.
•
Animation menu: The Animation menu appears in the fifth column. To open this menu,
position the pointer over this column, then click the inverted arrow that appears. The
Animation menu in the Keyframe Editor contains all commands found in the Inspector’s
Animation menu, plus several additional commands:
Animation menu
•
Enable/Disable Animation: Activates or deactivates the keyframed value. Choosing Disable
Animation hides the keyframes you set, restoring the parameter to its default value.
However, the keyframes are not thrown away. Choosing Enable Animation returns the
parameter to its last keyframed state.
•
Reset Parameter: Removes keyframes and settings for the parameter, restoring the
default value.
•
Add Keyframe: Adds a keyframe at the current frame in the Keyframe Editor. If the playhead
is positioned on a frame where a keyframe has been added, this command is unavailable.
(Alternatively, you can use a keyboard shortcut (Control-K) to add a keyframe.)
•
Delete Keyframe: Deletes the current keyframe. This command is available if the playhead is
positioned on a frame where a keyframe exists.
•
Previous Keyframe: Moves the playhead to the previous keyframe for this parameter. This
command is available if a keyframe exists earlier in the project.
•
Next Keyframe: Moves the playhead to the next keyframe for this parameter. This command
is available if a keyframe exists later in the project.
•
Interpolation: Sets the type of curve for the parameter. See Curve interpolation methods on
page 475 for examples of the different interpolation methods. Choose Constant, Linear,
Bezier, Continuous, Exponential, or Logarithmic.
