Aperture 3 terminology issue
While working in Aperture, I inadvertently activated a feature that I find unhelpful. that occupies valuable screen real estate, and that therefore I wish to disable; but, because I do not know what the feature is called, I cannot use the Help menu to figure out how to turn it off.
The bar that I wish to hide/disable is the bar with navigation/deletion controls at the lower portion of this partial screenshot:
. . . the bar with the red X button. red down arrow button, green up arrow button, etc.
What is it called, and how do I turn it off?
