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 was actually wondering the same thing but i've tried and i don't think you can. i think once you set it up then that's what it stays as. sorry ; -;
