Scale Keys Settings

In the Graph Editor and the Dope Sheet Editor use the Scale Keys Tool to scale a region of animation curve segments and the positions of keys in the graph view.
Note: There is also a Scale tool in the Graph Editor and Dope Sheet Editor Edit menu that has options here: Scale Keys options.
Note: You can change the size of keys appearing in the Graph Editor Graph view with the Key Size option in the Graph Editor section of the Animation (Settings) Preferences.

In the Scale Tool Settings window, there are two ways to scale keys in the graph view.

For more information, see Scale keys and Scale curves.

Type

Set one of the following options:

Manipulator

Scaling Graph Editor keys using the Manipulator

Scaling Dope Sheet Editor keys using the Manipulator

Lets you scale keys with a manipulator box style.
Drag-select keys and then click and drag a corner of the manipulator box.
Note: Graph Editor only: The manipulator box shows percentages to let you precisely gauge how much you are affecting the selected keys. You can also double-click the value to enter a custom value.
Gestural

Scaling Graph Editor keys using the Gestural Type

Scaling Dope Sheet Editor keys using the Gestural Type

Changes the way keys are scaled in the graph view so the mouse position, rather than a scaling box, determines the scaling vectors.
Middle-click and drag left or right in the Graph View/View area.
Only scale selected keys
When on, the Scale Keys Tool affects only selected keys. When off, Scale Keys Tool affects all keys.
Note: When the Only scale selected keys option is off, keys are scaled in a ripple mode.

You can also select Edit > Transformation Tools > Scale Keys > to open the Scale Key Tool options window. See Scale Key Options.
