Starting in "Example: Swap" (in the "Generics" chapter of "Intro to Ada"), there is reference, in text, to a procedure titled Generic_Swap. This procedure is not highlighted with orange text (as is typical of code references). It is highlighted with green AND orange text. The Generic_ portion of the procedure is green, the Swap portion is orange. Since green text is typically used for keywords, it seems like the interpreter thinks Generic_ should be highlighted as a keyword.
