Are there occasions when you’d like to print just part of an email message or web page? Here’s a technique you can use to print selected text from just about any application on your Mac. I’ll use an email message in Apple’s Mail application as an example.

• Open Mail and select a bit of text in an email message.
• Go to the Mail menu and select Services. From the sub-menu select Make New Sticky Note. (If you’re using an application other than Mail you won’t have a Mail menu. Instead, go to the menu named after your application. For example, if you’re using Firefox, select the text and go to the Firefox menu.)
• The application named Stickies will open and you’ll see a new sticky note on your screen that contains the text you selected in your email message.
• Go to the File menu and select Print.
• Click the Print button to print that sticky note.

That’s it! (You can delete the sticky note by clicking the small square in its upper left corner.)

You can use this same technique in Safari, Firefox, Word 2011 and most other Mac OS X applications. This technique will not work in some older Mac applications such as Word 2004 and Quicken 2005.

Sometimes an application stops behaving properly and doesn’t respond to menu commands or keyboard commands. When this happens, you’ll often want to use the Force Quit command to force the application to quit. There are several ways to issue the Force Quit command.

1. The easiest way is to click on the Apple menu and select Force Quit. A window will pop up listing all of the applications which are currently open. Click on the one that you want to force quit, then click the Force Quit button in the lower right corner. You’ll be asked if you’re sure that you want to do this. Click the button to indicate that you’re sure.

If the Apple menu is not responsive, you may not be able to use this method. In this case, try the next method.

2. Hold down the Option key while simultaneously clicking on the Dock icon for the application which you want to force quit. A menu should pop up after a couple of seconds. Select Force Quit from this menu.

If the Dock is not responsive, you may not be able to use this method either. In this case, try the next method.

3. Simultaneously press the following 3 keys: Command, Option and Escape. The Escape key is labeled “esc” and is above the “1″ key. A window will pop up listing all of the applications currently open. Click on the one that you want to force quit, then click the Force Quit button in the lower right corner. You’ll be asked if you’re sure that you want to do this. Click the button to indicate that you’re sure.

If none of these methods work then you aren’t able to force quit applications. Typically, the only option at this point is to force the computer to turn itself off. This is accomplished by pressing and holding the Power button for 5 seconds. The power button is the round button used to turn the computer on. Hold this button for 5 seconds. The entire computer will turn off and the screen will go dark. Press and release the power button to start up the Mac again normally.

Is your Mac’s screen cluttered with too many windows? Do you drag windows left and right, up and down, trying to find the window that you’re looking for? There is a better way to manage window clutter on your Mac. Apple offers a number of tools and techniques including Spaces, Expose, Minimize Window and others. This article talks about my preferred method. I use three different keyboard commands – hide application, Application Switcher and cycle through windows. Let me explain how to invoke each keyboard command. Then I’ll explain how to tie them together.

Hide Application – Nearly all applications can be hidden by pressing either Command-H or selecting Hide <Your Application’s Name> from the Application menu. For example, if you’re reading this article using Safari then click on the Safari menu at the top of your screen. Half-way down the menu you’ll see Hide Safari listed. Alternatively you can press the Command key and the H key to hide Safari.

Application Switcher – Not surprisingly, the purpose of the Application Switcher is to let you easily switch between applications. To invoke this feature simultaneously press the Command key and the Tab key. Then, release the Tab key. You’ll see a row of big icons appear across the screen. This row of icons is the application switcher. To use it, continue to hold down the Command key and then press and release the Tab key. Each time you press and release the Tab key you’ll see that the next application in the list is selected. If you continue to hold down the Tab key then you’ll rapidly advance through the list of applications. When you’ve selected the desired application from the list, then release all keys and the selected application will come to the fore-front. Hint: If you want to move through the list in reverse, then press Command-Shift-Tab.

Cycle through windows – Within a specific application, one can easily flip through all open documents and any other windows by simply pressing Command-tilde. The tilde key is the key to the left of the 1 key. The tilde is the accent mark that goes over an “n” in Spanish. To use this properly you need to depress the Command key and then press and release the tilde key each time you want to advance to the next window. Go ahead, give it a try.

Using all of these commands together. When I’m done with a given application, for a least a minute or two, and I want to switch to another application then I press Command-H to hide the current application. Then I press Command-Tab to invoke the Application Switcher and use it to switch to the application that I want to use. If I have many windows or documents open in this application then I just press Command-tilde to quickly find the document that I want. Then again when I’m done working on that document or application, I hide it and switch to the next application.  This lets me reduce window clutter and quickly find the document that I need.

Is your Dock over-crowded with icons? If so, then maybe you would benefit from using an application launcher. An application launcher allows you to open any application installed on your Mac using your keyboard. This page at Pure-Mac lists a number of application launchers. I’ve tried a few of them and prefer LaunchBar. This feature list gives you an indication of the myriad of things that LaunchBar can do.
