Thanks for that, Dale B. I was looking for something like that in the Graph Editor, but didn't know about the drop-down for the Y axis nor about CTRL trick:-)

RE: selecting the whole animation; can't you just select the start, scroll to the end then shift-click (like in word documents)? I thought I'd tried that and it worked, but maybe I was mistaken..

Slightly off-topic, I wanted a way to apply the BVH files to V4 but with "flat feet", not the "high-heeled shoe" effect that is her zero position.
I couldn't find a simple way to do it (maybe there's a way with the graph editor now I'm learning some more of its capabilities), so I wrote a Python script that does it for me:-)
The script simply goes through all the keyframes (which is usually all frames after loading a BVH) and subtracts 25 degrees off the "Bend" parameter for each foot. Takes about 5 secs to run on a 991-frame anim..
I'm trying to think up ways to use the same technique to correct other  "faults" (such as compensating for body-parts which are different in length from those assumed by the BVH), but that's not so easy..

Cheers,
Diolma
