GET THE DICTIONARY MEANING
If you want to get the dictionary meaning for a particular word, simply take the cursor over the word and double tap the trackpad using three fingers. The text will get highlighted in yellow and a pop up box will show you the dictionary definition and synonyms from the built in thesaurus.
SEARCH SPECIFIC FILE TYPES ONLY
While searching using the search box in Finder, type 'kind:' followed by the first alphabet of the file type you are searching for (example, type P for PDF or D for DOC). A drop down menu will show you a list of various file types to choose from. Select the file type you are looking for and then type in the name of the file to search.
REMOTELY WIPE DATA
If you have setup an iCloud account on OSX Lion, just by logging in to your account from another system, you can send a remote wipe command. This is useful to remotely wipe all the data from the hard drive in case of theft. Note that FileVault encryption service should be activated for this to work.
PREVIEW YOUR SEARCH RESULTS
When you search for anything in OS X Lion using the desktop Spotlight search icon in the top bar, you can get a preview of the search results. Simply move the pointer over one of the search results and it will show you a quick look panel with a preview of the particular file's contents. Note that this works with documents and images only.
LAUNCHPAD WALLPAPER STYLE
By default, LaunchPad displays the installed applications over a blurred image of your desktop wallpaper. If you don't like that look, then simply press 'Control + Option + Command + B' to switch between various background effect styles.
ADD DIGITAL SIGNATURES TO A PDF
Open a pdf file in the Preview application instead of Adobe Reader and press Shift + Command + A to bring up the annotations toolbar. Click on Signatures and select 'Create signature from iSight'. Now, sign on a blank piece of paper and hold it up in front of the webcam — it will save your signature digitally. Whenever you want to include your signature in a PDF, just select it from the toolbar and insert it on the page.
SECURE EMPTY TRASH
Hold the Command button on the keyboard and then alternate (right) click on the Trash icon on the icon dock. The pop up menu will display 'Secure Empty Trash' instead of just 'Empty trash'. The benefit of Secure Empty Trash is that the deleted files cannot be recovered by anyone using basic data recovery tools. Note that using the Secure Empty Trash feature takes more time to empty the trash than normal.
