How do powers work? I'm unclear on how to actually use at-will powers during combat. For example, when can I use Nimble Strike (as an Elven Ranger) and how do I make it happen?

If you look on pages 15 and 54 of they PHB they describe how to use at-will powers.
You can use them as often as you like. They represent simple tasks that do not put unusual strain on your character.
