From the source SKILL.md

Given an unknown macro pad, mouse button, foot pedal, or HID gadget, find out exactly what each button emits at the OS level — without guessing from labels, vendor docs, or photos. Cheap HID pads frequently ship with arbitrary or mis-labeled keycodes (the Jieli/Free3-P ships with buttons labeled top/middle/bottom emitting Ctrl+C/Ctrl+V/Ctrl+X — which isn't the cut/copy/paste convention; it's hardware-random).
