Use Scale Keys to compress or expand the amount of time between keyframes. Works both in Curve Editor and Dope Sheet modes. See Scale Keys - Time .
Proportionally increases or decreases the values of the keys, rather than moving the keys in time. See Scale Values .
Creates keys on existing curves. See Insert Keys.
Use this to draw new curves, or revise existing ones by sketching directly on the function curve graph. See Draw Curves .
Use this to reduce the amount of keys in a track. See Reduce Keys .
