Using the Manipulator Box
You can use the manipulator box to move or scale a group of keyframes. The
advantage the box has over simply selecting keyframes is that you can see the scale
borders.
To use the manipulator box:
m Hold down the B key (for box) and drag to select a group of keyframes.
The light gray manipulator box appears around the selected keyframes.
To move the selection:
m Position the pointer within the box, then drag.
To scale the selection in both the X and Y axes:
m Position the pointer at the corner of the box and drag. The box is scaled in X and Y
around the opposite corner you select—if you grab the upper-right corner, the center
of scaling is the lower-left corner.
To scale the selection in the X axis:
m Position the pointer along either side edge of the box, then drag.
