Moving 2 things at once

Woot I have learn how to animate, a little anyway.
I was just wondering how to move the same object twice at once, i am doing a dance and i want my model to do move his feet but slide to the side at the same time. I have done this as to seperate actions but i can’t get them to play one ontop of the other because the NLA editor only uses the bottom one.

You need to convert the action strips into NLA strips by hitting the “drowning man” icon . Otherwise the NLA will only play the selected action and not the others .

On my very basic way (basically, i’m issued from an artisant cultur… He, he!..) i would have had the side slide effect done with an Empty constraint… Wouldn’t this give me a new line on the NLA Pannel?
