Apple Motion 4 - Manual (Page 550)

• 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. 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.
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 pointer, click to add a
keyframe.
• Delete Keyframe: Deletes the current keyframe. The Delete Keyframe option is available
only 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 available only 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 available only 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 .
