416 Chapter 6 Keyframes and Curves
Enable Animation: This menu item remains unavailable until animation is applied to
the channel either by using the Record button or by directly adding a keyframe. Once
the channel has at least one keyframe set, the menu item is automatically renamed
Disable Animation. Choosing Disable Animation 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 again restores the channel
to its last keyframed state.
Reset Parameter: Removes all keyframes and settings for this channel. The parameter
value is reset to its default value.
Add Keyframe: Adds a keyframe at the current frame in the project. If the playhead is
positioned on a frame where a keyframe has already been added, this menu command
is unavailable.
Note: To add a keyframe, you can also position the pointer over the Animation menu
and press Option. When the keyframe icon appears next to the point, click to add a
keyframe.
Delete Keyframe: Deletes the current keyframe. The Delete Keyframe option is only
available if the playhead is positioned on a frame where a keyframe already exists.
Previous Keyframe: Moves the playhead to the previous keyframe for this parameter.
The Previous Keyframe command is only available if a keyframe exists earlier in the
project.
Next Keyframe: Moves the playhead to the next keyframe for this parameter. The Next
Keyframe command is only available if a keyframe exists later in the project.
Show in Keyframe Editor: This opens the Keyframe Editor and displays the selected
parameter’s keyframes and curves. For more information on working with the Keyframe
Editor, see “
Animating in the Keyframe Editor ” later in this chapter.
To set keyframes using the Animation menu:
1 Enable Record (press A), then move the playhead to the frame where you want to set
the first keyframe.
2 Change the value of the parameter you want to keyframe.
3 Click the Animation menu, then choose Add Keyframe.
A keyframe is added at the current frame.
Add Keyframe Shortcut
To quickly add a keyframe without accessing the Animation menu in the Inspector,
press Control+K. A keyframe is automatically added to the last modified parameter of
the object (regardless of the status of the Record button) at the current time.
