10 Commands to take a Screenshot in Mac OS X

I must agree with myself on this that switching to a Mac wasn't the easiest thing to do, I had to learn around new tricks to get my work done and also, for me, the experience was much different to what Windows had to offer, much better and more flexible.

Since the most usual and important task that I perform nearly every 10 minutes or so is taking a screenshot, so with time I managed to learn a couple of techniques to do it through different ways and here I am sharing them all as a future reference to myself and for other Max OS X users.
