I understand now. I have 12 bookmarks across the top on my screen on my bookmarks bar (I edited them down ), then just to the right on the end is a set of double arrows >>, I click on that and the rest off my bookmarks become available in a vertical list which can be put in the order I want. With my eyes I might have trouble trying to recognize 50 icons across the top of the screen, and heck I might not even remember what the icons stood for.
