We moved office we all got new wireless keyboards and mice in our flexible new office! 
The keyboard is a microsoft wireless keyboard 800 which has no differentiation between the main keypad the cursors/insert/delete section and the number pad. The function keys are too small to hit. All in all a pretty inept product.
I immediately put back in my thick heavy, wired chunky dell keyboard with full size keys etc. I love my solid old Dell keyboard!
