I have my Ergodox set up so I hold down a thumb key and it activates a layer so my right hand has arrow keys and pgup/pgdown/home/end right there on the home row.

I can't live without it now.

My keyboard is set up in a similar manner but it adds a point of complexity. Ctrl-Shift-Arrow is harder to use since the Fn key is trying to take up a thumb.

I still prefer that complexity to having to move my entire hand from the home row to use the arrow keys. I'm very used to it now.
