Third person controller & animation.. NEED HELP

Ok guys first of all sorry if i am asking noobish questions :(

I played a bit around with the default construction worker model that comes with unity 4. Everything works fine. The character is movable and animations can be seen when set corectly in animations and third person controller tab. Now I want to use the the third person controller with my own character and see some animations too. What do i have to set if i want it to play a walking move when im actually walking with the character?

I noticed that no animations came explicitly with my own character. So have just set my character to humanoid and set the bones etc.. Third party animations work fine in preview tab so i assume i set everything correctly.

I played a bit around with the animator and have an idle animation now. But how do i tell unity to play a move animation when i press forward key?

Thanks and regards F.
