I know that the space bar is used for a power up, F10 takes a screenshot, and Esc exits the application. Is there a list of function keys somewhere? Would it be possible to have a list of function keys popup on screen for reference? This could potentially be done by updating the menu that shows up when clicking on the application icon on the top-left.
