Scale Keyframes Together From "Medium Point" I have two key frames in order to make an object change location.  I decided to make it move faster, so I want to scale the key frames together.  However, when you select them and scale, both key frames will grow closer to each other, but they also start moving towards frame 0.
I want to scale both keys so that they move towards the middle of the original distance between them.  This would be like scaling two objects using the medium origin in the 3D view.  How can I accomplish this?
In the Dope Sheet, the position of the 2D cursor (the blue line) will be the pivot point:

As  atomicbezierslinger says, if you switch to the Graph Editor (CtrlShiftTab) you'll have the choice between Bounding Box Center, 2D Cursor and Individual Centers:

if you want the middle of your selected keyframes to be the pivot point, choose Bounding Box Center:
