// This sketch is set up to demonstrate the GhostInTheFirmware plugin. The left
// palm key will activate the plugin, virtually pressing each key on the bottom
// row in sequence, and lighting up the keys using the Stalker LED effect. It
// will type out the letters from A to N, but the right palm key can be used to
// toggle the custom EventDropper plugin to suppress USB output.
