How to remap F4 to Dashboard or Notifications on a MacBook Pro in Yosemite?

I had this working fine in Tiger thru Mavericks, but it broke in Yosemite. Pressing F4 now launches Launchpad, and only fnF4 triggers Dashboard.

Launchpad is useless compared to Spotlight or even the Dock. I'd much rather have the F4 key triggering Dashboard again, or even Notifications (which is really starting to come along).

I have:

• System Prefs / Mission Control / Keyboard and Mouse Shortcuts / Show Dashboard set to F4.


• Syst Prefs / Keyboard / Keyboard / Use all F-keys as standard function keys unticked.


• Syst Prefs / Keyboard / Shortcuts / Launchpad & Dock / Show Launchpad unticked.


• Syst Prefs / Keyboard / Shortcuts / Mission Control / Show Dashboard set to F4.

Ideas? Hopeless? Thanks!
