You can still move layers around in the layer order in the palette. Here you can see that I'm moving the oval fill shape to above the text layer, so that it is now hiding the text layer because of the layer order. The layers are still linked and will move together...

Here is a quick introduction to channels (which are covered more in depth in my video training with Basic Photoshop). In the Channels palette you basically have your different color 'channels'. I'm still waiting for the MTV channel...

Welcome to the Navigator tutorial. This is a cool little tool. I don't personally use it that often but you can if you want to. It basically shows you a smaller version of the entire image and the portions which are visible (depending on the zoom level)...
