Control Option Command

Macs are awesome.

1. Invert the screen

To freak out your friends just wait until they leave the keyboard for a sec and hit CMD – CTRL – OPT – 8.
In fact I used to do this when using my mac during lectures because the inverted screen was less disturbing in the dark.
To reset it just hit the aforementioned key-combo again.

2. Distorted browsing.

1. Set your Dock?s minimize effect to ?Genie? (or the hidden ?Suck? choice, using TinkerTool).
2. Open Applications ? Utilities ? Terminal.

3. Type “killall Dock” (no quotes) but don?t hit Return just yet.
4. Open Safari and load a decent sized website, like Digg.
5. Switch back to the Terminal, keeping the Safari window in view.

6. Shift-click the yellow minimize button of the Safari window, and hit Return to execute the command while the window is busy morphing.

The Dock process will be killed, and it will disappear, leaving the Safari window with nowhere to go. The window will freeze mid-transition. The cool part is that the window is still responsive, and you can scroll around and see the content transform in real-time.

The Dock automatically relaunches, so you don?t have to worry about breaking anything. Finish minimizing the window, or do CMD-W to close it.

(Via Command-Tab.)

3. Zoom with the scroll-wheel

Another functionality that was probably intended for accessibility but can be loads of fun as a prank on a less savvy friend. With a scroll-wheel mouse press ctrl and scroll the wheel to zoom the screen to some ridiculous proportion. Stand back and watch as your buddy panics. To really screw up someones day if the have a pre-Leopard Mac; Zoom the screen just one pixel. This results in everything getting slightly blurry and your buddy/mother-in-law will think there’s something wrong with their monitor.

4. Free psychoanalysis

1. Open a new Terminal window. (Finder -> Applications->Utilities->Terminal).
2. Type “emacs” (no quotes) and hit enter.
3. Press ESC and “X” simultaneously. “M-x” should appear at the bottom.

4. Type “doctor”.

This should launch the Eliza shrink-sim. Fairly silly stuff, but hey! Why shill out for a therapist when you’ve got one sitting in your terminal?

(Apparently you can play tetris and do all sorts of wacky stuff in the terminal. Find more at The Easter Egg Archive.)

5. Knock knock…

Open the “Speech” prefpane in System Preferences and activate “Speech recognition”. Tell your mac to “Tell me a joke” to get a plethora of inane knock knock jokes.
