> What I'm actually wondering is how much work it would be just to create a single button that's an escape key on a USB stick If you have a suitable Arduino (or compatible) lying around probably not a lot of work: https://www.arduino.cc/reference/en/language/functions/usb/keyboard/ https://www.arduino.cc/reference/en/language/functions/usb/k... It would depend if "Escape" requires a specific non-standardized scan code or not. (Even if it did you could also try sending the Ctrl-[ variety instead.) (It's even possible to get away with not using USB-specific hardware, like I did in the "old days": http://code.rancidbacon.com/ProjectLogArduinoUSB http://code.rancidbacon.com/ProjectLogArduinoUSB :D ) Random piece of keyboard trivia: On Mac OS X (and I assume current variants) each keyboard is a separate "entity" with e.g. separate state which includes caps lock state. This means that the USB "Capslocker" gag USB dongles that randomly toggled Caps Lock state didn't actually affect Macs.)
