If u want to learn how to perform an action, which feature of excel should u use?

Use help.

Explanation: Click on the "Help" Tab and then click on the left hand side icon which should say "Help", it has a question mark sign (?). After you click it, on the right hand side, a window should pop up, then type the search criteria.

i would say 3 because windows is the best but vista doesnt do updates anymore

8 track im pretty sure came first
