Windows 7: Anyone know how to crop a 3ds max animation?

I've got an animation, its 400 frames, but i only need frames 100-200, is there a quick way to just crop it?

This is all i need to do, i dont want to read countless tutorials on how to _make_ animations or anything, i'd be very greatfull if anyone could point me in the right direction cause max doesnt seem to have an option for it. (a quick step by step guide would be ideal)

I hope im not asking too much, and i hope someone is knowledgable enoguh to tell me how! Thanks

[Edit] Figured it out with help
