Lion Shortcuts are there to make our repetitive tasks a little bit easier but eliminating lengthy and complex sequences and condensing them into two or three keystrokes. Lion, or any OSX version for that matter, comes with a very diverse set of keyboard shortcuts. If you’re new Mac owner, you will definitely find these shortcuts very helpful in your daily tasks.
1. Application Switching.
Lion is very friendly to users who just love to multitask. There’s no need to minimize and maximize windows to switch between apps. Just press Command-Tab and a line of icons of your open applications will appear. Pressing it once will immediately switch to the next application. Pressing it several times will move the selection on the line. Release the keys once the appropriate icon is highlighted.
2. Showing / Hiding the Dock
The dock is a very convenient place to hold the apps you use the most. However, sometimes it can be distracting especially when you accidentally mouse over and end up launching an app you don’t want. And when you need all the screen real estate, hiding the dock can free up a few more spare inches.
To hide your dock, press Command-Option-D. Repeat the sequence to show the dock once more.
3. Hide Applications and Windows
Somebody shows up and you don’t want him to see what you’re doing? Short of buying a privacy screen, the quickest thing you can do is to hide the applications and windows you are currently using.
Command+H will hide everything. If you want to hide everything except the current application you’re on, Command+Option+H will do that for you.
4. Force Quit
On the rare occasions that your application suddenly wouldn’t respond, the best way is to force quit the application. As the name implies force quit will close the application and all associated windows with it. You can relaunch it after that.
If you know which app is giving you trouble, right click the icon and press force quit, but if you are uncertain which one is not responding or you would like to force quit several apps, press Command-Option-Esc. A dialogue box will appear containing all apps that are running. The problematic app will indicate ‘not responding’. Select the app and press force quit.
5. Go To Folder
If your Finder is a bit disorganized, a few keyboard shortcuts will quickly get you to where you want to go. In Finder, Command+Shift+H will take you to your home folder, Command+Shift+U to open your utilities folder and Command+Shift+A to open your applications folder.
There are many more Lion Shortcuts available but these are the most important to know.
