My F11 key no longer launches Launchpad. I blame Microsoft.
Brand new iMac with El Capitan. Running along spiffily until today using F11 as a keyboard shortcut for the Launchpad. (Yes, I have the Keyboard settings set to "Use... as standard function keys," but it does the same thing if I don't.)
This evening I installed Microsoft Office 2011 and a Wacom tablet and my F11 no longer calls up the Launchpad. If I'm in Firefox, it takes the app fullscreen. In other applications, including the finder it gives me a single "error" chime.
Now, I don't know whether Firefox was doing this before, but I'm assuming that my Office install is to blame. Is there a way I can make this behave the way I want it to without uninstalling Office? I'm happy to dump it in favor of Pages and Numbers, but I'm afraid it'll leave something on my machine anyway...
As an additional clue(?), if I log into my Guest account, I can get the F11 to call up the Launcher with no problem.
iMac with Retina 5K display, OS X El Capitan (10.11.6)
