Cannot find Zoom dropdown for Screen Canvas View
I cannot fin the zoom dropdown to "zoom in" or "zoom out" of the "screen" canvas view. I'm trying to see the full 1280 x 800 screen on one page.
I seems to be stuck a 100% view (see here http://prntscr.com/k5dwxj)
Any advise would be helpful. i'm a Macbook Pro with El Capitan 10.11.6
