After thinking about it overnight, I'm thinking about adding a button type that automatically binds its onclick method to either a given or automatically generated binding.

So something like

    ptg.KeyboardButton("Help")

or

    ptg.KeyboardButton("Action", binding=ptg.keys.CTRL_B)

These would create a button with a label such as "[H]elp" and "[B] Action", and pressing `CTRL_` + their button would activate them. If idea is fine implementation should really not take much time.
