Need help editing FPS animations

Hi

I’m working on an fps and i’m using the fps template with stock animations, I added a custom weapon (rifle) and noticed that the animations didn’t quite fit so I fiddled with the idle animation until I got it how I need it to look then selected the root bone of the skeleton and clicked the add key button from the toolbar, then I clicked apply and saved… The idle animation now works perfectly. But I can’t say the same about the others. Tried to find away to copy the newly created curved to the other animations but to no avail. I need to be able to get the exact joint positioning to the start of every animation I have but I have no clue how that could be done…

Any ideas?

The in advance
