Question for the Pure owners: I'm a programmer and I make heavy use of the arrow keys. Where I work we follow camel case (mixed case) convention for variables and whatnot so the Shift key is also important. I'm not a touch typist sadly and pretty much always use the right Shift key to capitalize. The question is: does the Fn key act as a modifier to the change the right side Alt, Shift, Control and Meta keys to behave as arrow keys? That is, can I hold Fn down while arrowing around or do I have to use the Fn+spacebar to lock into that mode and then unlock to return access to the right Shift key? I seem to recall someone saying the Pure had the latter behavior but I wanted to be certain.
