TUAW Tip: Option-clicking the green button

When iTunes 9 changed the behavior of the green "maximize" button to shrink the player to the mini player, I adapted quickly. Option-clicking is pretty easy to do since the option key (unlike control) is on both sides of my laptops' keyboards. But I forgot that option-clicking the green button on windows in OS X does other things too.

For many applications, simply option-clicking the green button will "maximize" all the open windows of that application. Of course, maximize behaves differently in some applications. For example, option-clicking the green button in Safari makes all the open pages taller, but not wider. That's by design in Safari, and I rather like it. If you come from Windows, however, you'll be mortified that the window does not occupy the entire screen. In Firefox, it does indeed maximize to fill the screen. It's a matter of preference, but the key point: option-click will max all open windows of that application. Some are "smarter" than others.

As our last trick, try option-clicking the green button Calculator. It toggles between the expanded, scientific calculator to the programmer's calculator to regular calculator. Neat!
