This is a version of the Key Manager script by Randy Kreitzman that I modified to work with TCB controllers instead of just Beziers. It allows you to change the tangent type - ease in/out and continuity for a bunch of selected Track View keys all at once. You can also shift the selection now - and affect prev/next keys as well. Works in MAX r2.5 - r3 and r4. Version 5 now updated to support Continuity and Bias adjustment for TCB's.
