Beebs, a couple of suggestions:
When you are using the touch controllers, this is generally always the case in apps/games:
1) Tapping the smooth button at the bottom of the right controller (the Oculus button) temporarily takes you back to Oculus Home where you can quit the app, change settings, etc. Tapping it again takes you back in. Holding the same button down resets your view to what direction you are facing, but it has mixed results depending on the app.
2) The same button on the left controller is normally the menu for that app/game. For example, in Nature Trek VR, that button opens up the menu of interactive objects you can throw out into the scene you are in.
3) Most of the time, the front triggers are how you interact with things and grip onto them in VR, though depending on the app, the side triggers are also used (for example, in Ocean Rift, the side trigger makes you swim).
4) The thumbsticks are normally used to turn your view, and in games with teleporting, they are often used to indicate what direction you want to teleport. This is a bit inconsistent among apps but you learn after awhile what does what.
5) In the browser, when you are trying the WebVR stuff, I believe you press the menu button on the left controller to get back to the browser view, then B on the right controller to go back a page.
6) If you are confused about which controller is which, the side trigger should be on the opposite side of whatever hand you have it in (the side trigger is on the left on the right controller and on the right on the left controller). That is where you naturally put your middle finger while holding the controller.
Lastly, if you are looking for something impressive, check out the app Wander. It's not free (I think it is $10) but it is worth every penny. It uses Google's street view imagery in an amazing way that basically lets you explore anywhere in the world. I can spend hours in it looking around different places.
Please feel free to bug me with any questions you have, and also add me as an Oculus friend sometime - my user id is GrandTheftGato.
