What I'm looking for is a USB button that can be bound to a key on the keyboard (aka backspace, for an abort button) I want to play KSP with a big red button I can press to abort. I've seen a few, but I'm not paying £80 for a simple button... I've seen cheap buttons, but I doubt they are USB capable, and I have no soldering equipment. I thought of taking apart an old mouse and using that, but I need the actual button too. If anyone knows where to find this, please post below. Thanks!
