Pan in animation controller view without middle mouse button

So just ran into a weird problem on my laptop where the states in my animation controller view are not fully visible. Maybe I'm an idiot but I cannot for the life of me figure out how to pan sideways. I think this is done with the middle mouse button but I don't have one on my laptop. Is there another way to do this?

Thanks

 

Ok I started randomly trying a bunch of thins and managed to figure it out right after posting this lol. In case anyone else is wondering, you hold down alt+left-mb and drag your mouse to pan.

 

Exactly what I was looking for

 

thanks by the way i tried a lot also . and in the end i did it with alt + left click + touch pad (in a laptop touch pad ) . i did it before in Blender with 3D designing and it's awsome without wheeler mouse....

 

Years later... came to say that it's Option + Single Click on a macbook.
