How do I change speed of default animations?

Hello,
How do I change the speed of default animations?
Say, I wanted to make the animation for walking faster without changing speed?

It appears you need to upload your own animation to replace the default one:

That being said, you could possible download the default one, change its keyframes, and re-upload to replace the default ones (which are available here: Using Animations in Games)
