I got a WASD mechanical keyboard with mac mode keys which has the all the media shortcuts such as play, pause, volume up/down etc except for screen brightness control. Even though in System Preferences F1 and F2 are set up to control the screen brightness for my iMac, they don't work when I press them on their own or in combination with Fn/ Command/control/etc.
Is there a way that I can have keyboard shortcuts to screen brightness control?
