Shortcut to access Sound Preferences on Mac OS X

Sound

When you click on the sound icon that is docked at right corner of the menu bar, it displays a slider for you to adjust the volume. To access the advanced sound preference, you can Option-click on the same icon to reveal a menu that allows you quick adjustment of the input and output devices, and also access the Sound Preferences.

The Sound Preferences can off course be accessed via the normal System Preferences->Sound. A keyboard shortcut to get to the same Sound Preferences is to hold the Option key while pressing the Volume Up, Volume Down or Mute button on the keyboard.

Quickly Hide Apps in Mac OS X

Mac OS X has some nifty shortcuts for hiding apps, useful when your boss or your partner is coming over while you’re doing ‘something’ on your Mac.

Use Command-H to instantly hide the app you’re currently using. The companion shortcut is Command-Option-H which hides all apps except for the one you’re currently using.

You can also use Command-M to minimize current window of the app you’re using. This is not as effective as Command-H as it is not instant. The companion shortcut key is Command-Option-M which minimize all windows of the app you’re currently using.

As a last resort,  you can always press Command-Option-Shift-Q to logout immediately.

CUPS under Mac OS X

We manage our printers and print jobs using Mac’s System Preferences->Print & Fax. Beneath the hood, Mac OS X is using a powerful printing system called CUPS. Turns out that CUPS has a web interface for you to manage and administer printers and jobs on your Mac.

To view the web interface, just point your browser to [http://127.0.0.1:631/](http://127.0.0.1:631/).

CUPS (some say stands for Common Unix Printing System) is by Michael Sweet and debuted in 1999. It is a free software under GNU General Public License and is also the default print engine for several Linux distributions such as Red Hat. Apple adopted CUPS since Mac OS X 10.2 in March 2002. In February 2007, Apple hired Michael Sweet and purchased the CUPS source code.

Screen Capture Shortcut In Snow Leopard

Mac OS X comes with a capable screen capture tool built-in. You probably already know that using *Command-Shift-3* is for capturing the whole screen, and *Command-Shift-4* will give you a crosshair cursor to choose the area of the screen you want to capture. Both *Command-Shift-3* and *Command-Shift-4* will output the screen capture as PNG file to you Desktop with a name “Screen shot xxxx” where xxxx will be the timestamp.

Instead of capturing to file, you can capture the image to Mac OS X system clipboard memory. This will allow you to paste the screen image into another application such as Photoshop or Pages. To capture screen into clipboard memory, use *Control-Command-Shift-3* for whole screen or *Control-Command-Shift-4* for portion of screen.

You can also capture specific window or object on the screen using the *Command-Shift-4* or *Control-Command-Shift-4* screen capture shortcuts:

* Press Command-Shift-4 or Control-Command-Shift-4. The cursor changes to crosshair.

* Press the spacebar to toggle the cursor into a camera icon.

* Move the camera cursor to the window or object that you want to capture. The window or object will be highlighted when the cursor is over them.

* Click the mouse anywhere on the highlighted window or object to take the screenshot.

Using Preview For Basic Image Editing
