Paw keyer

I've shown a couple images of HUD specs. Now here's the input to go with the output. The keyer proper looks like the molded rubber grip of a bicycle handlebar. Running across the top of the keyer proper is a cushion that conforms to the contours of the wearers paw pads. On the bottom of the keyer body are four grooves shaped to fit the four middle digits, each with a button. Flanking this row of buttons are two thumb clusters, each with a button or two as well as a trackpoint. A strap goes all the way around the keyer. the paw slides through the top, and the wearer curls their fingers down and through the bottom part of the strap. There is a knuckle cushion on the strap that presses against the ground as the wearer walks.
