When you select multiple keyframes in the Graph Editor, a free-transform bounding box appears.
1 Switch to the Graph Editor view and display the keyframes you want to adjust.
Using the Selection tool, do one of the following:
2
• To select keyframes, Shift-click the keyframes or drag to draw a marquee around the keyframes.
• To select all keyframes for a property, Alt-click (Windows) or Option-click (Mac OS) a segment between two
keyframes.
Do any of the following:
3
• To move keyframes in time or value, position the pointer inside the bounding box and drag. Shift-drag to
constrain the move horizontally or vertically.
• To move keyframes in time or value by scaling the bounding box, position the pointer on a bounding box handle.
When the pointer changes to a straight, double-sided arrow
constrain the ratio of width to height. Ctrl-drag (Windows) or Command-drag (Mac OS) to scale around the
bounding box's anchor point. When dragging a corner handle, Alt-drag (Windows) or Option-drag (Mac OS) to
move only that handle.
Scale by negative amounts to reverse the keyframes in time.
• To taper keyframe values vertically, Ctrl+Alt-drag (Windows) or Command+Option-drag (Mac OS). Tapering
keyframe values allows you to reduce or expand the amplitude of a repeated animation.
• To move one side of the bounding box up or down, Ctrl+Alt+Shift-drag (Windows) or Command+Option+Shift-
drag (Mac OS).
• To move the bounding box's anchor point, position the Selection tool over the anchor point until the tool changes
to the Move Anchor Point tool
