Fast Forward in QuickTime & Speed Reverse with Gestures
You can fast forward or quickly rewind any video playing in QuickTime Player in Mac OS X (or Windows if you go that direction) by using a trackpad or magic mouse.
This is really easy to use but it’s best followed along and tried out yourself than just reading a tutorial, so launch QuickTime Player with a movie of some length so that you can test this out yourself. The QuickTime app is located in the /Applications/ folder of OS X, older versions may be stored as QuickTime Player in the Utilities folder too.
