In the above graphic of the screen this is only a small…and I mean small portion of the functions that are displayed on a 991A.  There are around 156 menu items that you can bring up as well as a secondary menu (not shown) that allows you to tweak your settings in a bit faster way.  This gives you a brief idea and understanding of what to expect.  I urge you to check out videos on Youtube from creators that have more in-depth and closeup reviews on the numerous functions within the 991A.
