Keys menu
Align to Cursor
Use Align to Cursor to move selected keys to the current time. Select the keys to align using Move, Slide, or Scale.
Align to Cursor is useful for taking a group of scattered keys and moving them to the same time location.
Align to Cursor is available in Dope Sheet and Curve Editor modes.
Align Keys to Cursor ignores the state of Snap Frames, and always uses the exact time set by the time slider.
To move all selected keys to the current frame:
(Move Keys),
(Slide Keys), or
(Scale Keys).
The leftmost selected key in each track is moved to the current time. Multiple selected keys on the same track maintain their relative distance from the leftmost key.
