Reset Apple Keyboard Shortcuts I have a new Apple Keyboard, up until recently pressing the F4 key used to activate Launchpad (Fn keys are set to do as the image on them) but mow it does nothing. I tried the keyboard with another mac and it worked as expected (pressing the F4 activated launchpad). How do I reset the settings on my mac so the F4 key works as I want it to?

PS. I tried going to System Prefs->Keyboard-> reset defaults with no luck.
On System Prefs->Keyboard-> Keyboard Shortcuts you need to click on Launchpad &amp; Dock on the left, then make sure "Show Launchpad" is checked.
