Wizzoboy pretty much answered your question, but I thought I'd chip in with a couple of things that I've found. I tried using the faders in the mixer window to write automation but I wasn't fond of the method as it creates a whole bunch of automation points in so doing. Instead, I use the edit window with the volume showing. Then, for example if I want to fade out at the end of a track. I use the hand tool to click on the volume line at the point I want to start to fade (which creates an automation point), and click again at the point I want the fade to end. I then click and hold the 2nd point and drag it to the bottom (or infinity). This way you'll have 2 automation points and when you watch it in the mixer window (with "auto read" mode on) it will show a nice smooth fade, and it looks better in your edit window.
