Please do give us more description of what you want to achieve or better yet a screenshot so we can give you more specific recommendation. For the mean time, check the following:
If I understand this part correctly: I would like to have a suite of buttons that allows for full screen display, return to a normal screen, forward and back pages, what you want is a button that will enable a fullscreen popup? If that is correct, please check Convertplus for the popup and use manual settings. With manual settings > Launch with a CSS class, we can use a normal button element, add a class on the button element for the popup/screen display.
Hope this helps.
