I put my lenovo laptop into yoga mode. Can't access the keys very easily, especially shortcuts that require two buttons to be pressed at the same time. I've programmed my wacom pen to do a few things but that is only 3 buttons. Is there a USB bracelet that will let you program certain buttons to it? I feel like something like that should not be difficult to build on my own or have someone build at cost. What would I need to get started?
