What does the shading around some 48 series keys indicate?

Those keys, with only RS- (aqua) shift labels are applications, typically with unique UI, often a pop-up menu, etc. Each of these applications also have a series of soft-menus, accessed by LS- (purple), which are not listed on the keyboards; since they are related to the applications, there is no need to add another (purple) label. The shading under these keys is to remind you both that they are applications and also have associated menus.

Note that CHARS, MODES and MEMORY are similar (special Apps and associated menus) but don't include the shading, probably to avoid obscuring the Alpha labels.

But c'mon, this is explained on page 4 of the manual. Please give it a try to lookup simple questions in the manual, and save Forum questions for those that need background, insight, history, etc.
