There is a Stealth button, but it only appears if you are in Mouse View mode. If you are in Mouse Cursor mode, then simply clicking such that you move very slowly does the trick. In fact, it is possible to move more slowly in cursor mode than in view.
Here's the deal: stealth is always checked when you approach an enemy. It is checked whether you are running, walking, sneaking, crouching, jumping, dancing, whatever. It doesn't matter how you approach, it will be checked. HOWEVER, your movement speed is what greatly affects how well you do--obviously, walking toward an enemy is more stealthy than running. The only thing--only thing!--the stealth button does is make you move slower. That's it. But, moving slower means you are better at sneaking, so it's a good thing. And yes, you now you're successful because they don't turn around to face you. And with a high skill, it is possible to sneak up on someone while running full tilt.
Backstab is also a check, and it is checked each time you hit an enemy from behind. It doesn't matter if they are aware of you or not--you can often backstab someone when they turn around to negotiate a corned they're stuck on.
