Thank you for this, as I am a mac user. Before you taught me aboutt the [cmd]+[shift]+. I always used a program called Snapz Pro, and my trial ran out. Just as a question I hope you can answer, where would I find these snapshots?
Also, I use fireworks not photoshop although I use it as well I use it rarely. I believe that fireworks works pretty much the same. For those of you who are firworks users.
