Window -> Previewer. Find the unit you're looking for, double click the .m3 file. Once you do that the model should appear on the screen. if you don't see it, try pressing the Zoom to Fit button (button with four arrows).
Underneath the blue preview panel you should see an item called Animation Layer. Right click that and then change animation to whatever is available for that unit. When you are done viewing that model you must select it and press delete, otherwise when you double click on a new .m3 file it would just be placed on top of the currently viewed model.
As the title says, where can I see all the animations available(for a specific unit)?

Also numpad + cycles through each animation. I tend to use that when I'm perusing the previewer.
