We are using standard keyboards in our office, but hardly touch them. Our set consists of a large trackball for the right hand(logitech optical trackman) & the ever revered nostromo programable keypad for the left hand. wouldn't know how to draw without it & only about $25-$30. Using keyboard for typing notes only. Got tired of all the ctl-atl 3 finger keyboard dancing that archicad seems to love & programed it all to single keys on the nostromo
