Eu queria saber se havia um nome para esse marcador?
É um marcador de parada de tabulação esquerdo (no Word para Mac).
Why it is not present on the right document?

You can set the following types of tab stops:
- A Left Tab stop sets the start position of text that will then run to the right as you type.
- A Center Tab stop sets the position of the middle of the text. The text centers on this position as you type.
- A Right Tab stop sets the right end of the text. As you type, the text moves to the left.
- A Decimal Tab stop aligns numbers around a decimal point. Independent of the number of digits, the decimal point will be in the same position. (You can align numbers around a decimal character only; you cannot use the decimal tab to align numbers around a different character, such as a hyphen or an ampersand symbol.)
- A Bar Tab stop doesn't position text. It inserts a vertical bar at the tab position.
