Saji was exploring the Themes menu for a presentation she just started working on. She found one she really liked, but wanted to look at the next one just to check it out. Nope, she still likes the previous one better. What's the quickest way to get it back?

a. scroll up to the beginning of the Themes menu and click through until she finds it again
b. click Ctrl+Z and the cool theme will be restored
c. click Ctrl+F and type in the name of the theme
