When resetting my Prime, which I have only a few days now, because it didnt respond to keystrokes, I saw the green Annunciator 'ALG' just left of the angle mode. It is not mentioned in the manual. What does it mean? It vanished after changing home settings, and I cannot find a way to reproduce it. While active, the entry of functions had changed and all entries were enclosed in apostrophes. Is there any documentation about it?

That shows up when you are in RPN entry mode and the cursor is inside an algebraic object.
