After realizing my keyboard mappings are a pain in the ass when I move from Mac to Windows and vice versa, I bit the bullet and decided to blow away the home and page-up keys on my keyboard.
The instructions on the Kinesis site are a little hard to read, so here's my own documentation - some instructions on putting the 'Windows' key or the Mac 'Command' key onto the 'Home' and 'PageUp' keys for your Kinesis Contour keyboard.
