On the site it says: for e-book applications you can set this button to turn over pages (single press for scroll down, press'n'hold for scroll up).

How do you do this? Changing the configuration for ubook reader to scroll left, right, down with ubook in full screen still makes it function "normally".

In my case, button 1 is still opening up file explorer and button 4 still minimizing to the today screen.

You'd have to set it up to record screen-presses or menu-presses; Vito can macro actions, which is where the 'set it to turn over pages' feature comes in.

 

Care to give a step by step guide? I'm not familiar with macro
