LocoScript's menu system enabled users to add, singly or in combination, a range of sophisticated typographical effects: monospaced or proportional character spacing; normal or double width characters and spacing; various font sizes; bold, underline, italics, subscript or superscript, and reverse video. All of these except those that affected font size and spacing were displayed on the screen. Reverse video was an on-screen reminder to the user and was never printed, while the other effects were printed, except on daisy wheel printers.
