 ## Theory of Operation

+- Hub16 works by presenting a uniquely identifiable key to your computer, which can be intercepted by a intermediate layer of software on your computer, and can then be processed by the OS as required.
 - This works by "wrapping" a normal key press with a modifier key to create a unique key, just like pressing SHIFT changes the key shown on your screen when pressed in conjunction with a key on your keyboard.
 - However, as CTRL, SHIFT, ALT etc are commonly used they would not be very helpful to generate a unique key, so we instead use F13 - F24 as most keyboards do not have these, but are still valid keycodes.
-- To achieve this, when you press a key, Hub16 first sends a modifier key (e.g. F23) before pressing down the key you touched. Upon release of your key, it releases the modifier, allowing the computer to pick up that Hub16 has pressed a key.
