This is a Generic Layout LScript that deletes all keys except the first from every channel of the selected object. This simple script was developed as a teaching aid.
WARNING: this script doesn't have any interface. When you run it, it will kill the keys of the selected object without asking you if you really want to.
If you like the functionality of this LScript, check out the Mot-ify plugin from TM Productions. It is much more powerful than Key Killer.
I take no responsibility for any grief these Lscripts may cause you and make no warranty regarding their effectiveness.
