Answer:
The TAB key
Explanation:
Sam would use the TAB key, located on the left side of the keyboard, to move around his document to add stops and format its information properly.
Pressing the TAB key will introduce a tab code in his document, which is like moving ahead by a certain number of spaces (5,6, 10 spaces for example, depending on the configuration of the document), but without using spaces, using a tab which is a much better option to position, align things up.
