问题
1) I looked read the article on microsoft's page where icons are described but I couldn't find the icon "Play Button with vertical lines" (it is accentuated with a red line in the image below). What does it mean?

2) Further more the purple Cube has according to the provided link two meanings:
- Method or Function
- External Declaration
So isn't that confusing?
回答1:
It seems to be a "Group Macro" glyph:
