Precision Keyframe Editing

There are several precision keyframe editing controls available to you in the form of hotkeys. The following section lists the hotkeys, their function, and how the keyframe appears in the editor--see Curve Editor and The Track Editor.

Other hotkeys are available for keyframing--see Appendix A, Hotkeys.
