Launch Application with Keyboard Shortcut?

It's probably conflicting with an existing shortcut. Go to System Preferences > Keyboard > Keyboard Shortcuts to view, modify, add and delete shortcuts.

 

Since LaunchPad is not an existing menu command, I don't think you can set it to launch with a keyboard shortcut natively. Quicksilver can do that, however, and also possibly Alfred or other shortcut managers.

Use BetterTouchTool

This app can be used for many things besides opening applications. First download BetterTouchTool here and make sure it opens on startup. Then open it. Once you have opened it, click on the menubar icon and click "Preferences". Click "Gestures" on the top and then "Keyboard". Then click "Add new keyboard shortcut" Click under "Keyboard Shortcut" and define your shortcut, and under "Predefined Action" drop down menu, click "Open Application / File / Script..." and a menu will come where you choose the application you want to open. Click on your desired application (launchpad is in the applications folder...) and then close the preferences window. That's it! You're done! By the way, this app can be used with gestures on trackpads and mouses and many other keyboard shortcuts.


PS: I don't think you can choose "command F3" because it is taken by the "show desktop" command. I changed my launchpad shortcut to "command enter" in system preferences and it works just fine...
