I was surfing around and found some cool tricks for OSX. Some are useless, some are more useless than others and some are actually useful. I'll let you decide what is what for you. MegaZoom While holding the control key, use your scroll wheel and scroll up and down to zoom the screen. In-Line Dictionary We all know about the ability to highlight words and right click to use the dictionary to define a word. But try this. Put your mouse over a word, then hit control + command + D and it will define the word in line, without opening dictionary. Negative Space If you randomly want to turn everything negative on your screen, try the following: control + option + command + 8. Slow Genie Effect If you hold the shift key while minimizing a window (double click the window or the minimize button) it will slow down the genie effect. Fun to watch. You can do the same when clicking on it on the dock to restore. Feel free to add more!
