On my Kinesis Advantage2, I have added the following mini touchpad (attached via velcro and 3M double-sided tape for the cable): https://www.ergonomictouchpad.com/mini_touchpad.php https://www.ergonomictouchpad.com/mini_touchpad.php The touchpad is in the middle area right above the right-thumb keys, within easy reach of my index finger without having to lift from the home row. Works great.
