Previewing your Type very quickly
Serif or sans serif? Oblique or Avant Garde? I am from more of a "Yeah, that looks appropriate" school of font usage. If you would like to cycle through your fonts to see what looks good, first commit the type. Once the type has been committed, click on the font name in the Character panel (Window>Character). With the font name highlighted, press the Up and Down Arrow keys to move through different fonts.
