Graph Editor - Editing

Tools and menus for the F-Curves in the Graph Editor.
By default, when new channels are added, the Graph Editor sets them to Edit Mode. Selected channels can be locked by pressing ⇆ Tab.

Basic Tools

These are some basic tools to modify the curves and keyframes.


Active Keyframe Panel.
Grab/Move selected keyframes G
Rotate selected keyframes R
Scale selected keyframes S
Additionally, for translation and scaling, you can lock the transformation along the X (time frame) or Y (value), as usual by pressing X or Y during transformation.
For precise control of the keyframe position and value, you can set values in the Active Keyframe of the Properties Region.

Clean Keyframes

(AltO or Key » Smooth Keys) There is also an option to smooth the selected curves , but beware: its algorithm seems to be to divide by two the distance between each keyframe and the average linear value of the curve, without any setting, which gives quite a strong smoothing! Note that the first and last keys seem to be never modified by this tool.

Sampling and Baking Keyframes

Sample Keyframes ⇧ ShiftO
Sampling a set a keyframes replaces interpolated values with a new keyframe for each frame.
