Using Mixamo Actions

HI Folks:

I have a character that I rigged in Mixamo, I also found several actions that I want to use with that character to make a short martial arts sequence

The character is in a .fbx file called Base Manequin.fbx

It will go something like this

Character walks in - Walking.fbx
Character Comes to the ready position - mma idle.fbx
Character throws a spin kick - Inside Crescent Kick.fbx
Character returns to the ready position - mma idle.fbx
Base Manequin.fbx (300.8 KB) Inside Crescent Kick.fbx (456.9 KB) Mma Idle.fbx (510.0 KB) Walking.fbx (355.2 KB)

I could really use some guidance. There are old videos but using 2.79 does not have the same options

Thanks
