Edge Animate, create "Next" and "Back" buttons that play from current position

Hey Everyone,

I'm trying to do something fairly simple but I could use some help in getting it to work and couldn't find any examples out there of this... here's all i'm trying to do.

I have animations along a timeline with labels and stop points for 1, 2, 3, 4, 5.  I want to create simple "Back" and "Next" buttons that will get your current label/position and play forwards or backwards to the next or previous label/position.  My attempt to show what It looks like logically in text:

Back  1 - 2 - 3 - 4 - 5  Next

And that's it, I know someone must have already done this or knows how, any help would be greatly appreciated 

Cheers,

Jeff
