I may have a simpler solution: a small touchpad like this: http://www.ergonomictouchpad.com/ergonomic_touchpad.php
I would have to shorten the cable significantly and run it inside the enclosure. They make an even smaller version, but inexplicably it has a PS-2 connector and requires a USB adapter -- way too large for my enclosure.
Here is what the enclosure looks like now:
It is basically a 3D Printed enclosure for a Raspberry Pi 3, a Chord Mojo portable DAC, 4 SD cards in SD Card readers attached via USB, a 5300 mAh Lithium battery, and a Tontec 3.5" Screen. The Chord Mojo is attached to the Pi via USB. The purpose is to hide all the cabling between the storage, source, battery, and DAC. I'm using the Chord Mojo because it provides tremendous sound quality and is able to drive full-size headphones.
very good DAC
