By the way, the amputate example can be found in the P3 manual. Amputate cannot be found in the P4 index, however, information on this topic can be found by looking in the index under "visible". Now that may seem like an appropriate correction, however, what about all those new P3 users (getting the program for free) who are learning to call it "amputate". When they get to P4 or P5 they're not going to know where to look.
