If tacit knowledge is "knowledge in the fingers", then my tacit knowledge of how to interface with a computer is all busted up on this Mac. I'm struggling to get the basic stuff done, moving my fingers, but what I want to happen, doesn't. I can feel a tension building in my shoulders, in my back, in my gut. Must. Not. Throw. Computer. Against. The. Wall.

I know I can remap the keys to work more like windows. I will. Otherwise I may go mad.
