Ergo split keyboard detachable num pad and mouse
I want an ergonomic keyboard (cheap) that can tent and split for angle. Further I suggest the main keyboard act as a USB hub into which the detachable number pad and mouse can be plugged. The num pad and mouse attachments should clip to either side of the keyboard or middle. And mouse options such as touch pointer (like a laptop), or trackball, and a scroll wheel. I do not yet appreciate a mechanical key, and would like this to be cheap!
