Keyboard Modifiers for the Pen Tool
To use the Pen tool most efficiently, use these keyboard modifiers:
Â Hold down the Option key while the Selection tool is active to temporarily enable
the Pen tool, then click in the keyframe graph area of the Motion tab or the
Timeline to add a keyframe at that point.
Â To remove the keyframe with the Pen Delete tool, hold down the Option key and
click an existing keyframe.
In addition, you can Control-click a keyframe and choose Smooth from the shortcut
menu to add Bezier handles to the keyframe. See “
page 310 for information on Bezier handles.
