To Edit Multiple Keyframes In The Graph Editor - Adobe AFTER EFFECTS 7.0 Manual

To edit multiple keyframes in the Graph Editor

You can edit and move multiple keyframes simultaneously using the Graph Editor. When you select multiple
keyframes with the Show Transform Box button toggled, a free-transform bounding box surrounds the selected
keyframes, and an anchor point appears in the center of the bounding box to mark the center point for the transfor-
mation. You can move the selected keyframes in time or value by dragging the bounding box or its handles. You can
also change the position of the anchor point.
Adjusting a free-transform bounding box in a value graph moves the selected keyframes in time and value. Adjusting
a free-transform bounding box in a speed graph moves the selected keyframes in time only.
When you select multiple keyframes in the Graph Editor, a Free Transform bounding box appears.
Switch to the Graph Editor view and display the keyframes you want to adjust.

•
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 point, Alt-drag (Windows) or Option-drag (Mac OS) to
move only that point.
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 , and then drag to position the anchor point.
, drag the bounding box to a new size. Shift-drag to
