kpScaler-izer: After needing to precisely scale some animations in Maya, I wrote a script that takes a range of selected animated attributes and maniplulates them based on a set of user adjustable settings. In the top example, I am reversing the animation by negatively scaling the keyframes, using the 0 time frame as the pivot. In the bottom example, I am scaling the keys out by exactly 1.5 times with the scale pivot set at 0 time frame
