You can change keyframe values in the Channel or Track View of the Animation Channel Editor.
To gesturally change keyframe values:
- In the Animation Channel Editor, select the channel that includes the keyframes you want to change.
- Click Frame to view the channel.
- From the Tools box, choose Select.
- Select the keyframes. To select multiple keyframes, press Ctrl+drag to create a rectangular selection.
Note: To select keyframes in only the selected channel, press Ctrl+F and drag a rectangular selection around the keyframes you want to select.
- Drag the keyframes to the new values. Press Alt to snap the frame value (vertical axis) to the nearest integer. Press Ctrl+Alt to snap to the nearest multiple of ten.
Note: Enable Track Snap on the Filter tab to snap keyframes to frames (not in-between frames). Or, press Alt+Z to snap when Track Snap is disabled.
To set a specific value for a keyframe in the Animation Channel Editor:
- Select the Channel that has the keyframe you want to change.
- Set the positioner to the frame where the keyframe is located.
- Click the value next to the channel name and enter a new value in the calculator. Or click the number and drag to change its value gesturally.
