A menu must communicate to the user information about:

  • The nature and purpose of the menu itself.
  • The nature and purpose of each presented choice.
  • How the proper choice or choices may be selected.

Menu Titles 

  • Main menu:—Create a short, simple, clear, and distinctive title, describing the purpose of the entire series of choices.
  • Submenus: — Submenu titles must be worded exactly the same as the menu choice previously selected to display them.
  • General: —
    • Locate the title at the top of the listing of choices.
    • Spell out the title fully using either an:
      • Uppercase font.
      • Mixed-case font in the headline style.
    • Superfluous titles may be omitted.

Menu Choice Descriptions 

  • Create meaningful choice descriptions that are familiar, fully spelled out, concise, and distinctive.
  • Descriptions may be single words, compound words, or multiple words or phrases.
    • Exception: Menu bar items should be a single word (if possible).
    • Place the keyword first, usually a verb.
    • Use the headline style, capitalizing the first letter of each significant word in the choice description.
    • Use task-oriented not data-oriented wording.
    • Use parallel construction.
    • A menu choice must never have the same wording as its menu title.
    • Identical choices on different menus should be worded identically.
    • Choices should not be numbered.
    • Exception: If the listing is numeric in nature, graphic, or a list of varying items it may be numbered. 
    •  If menu options will be used in conjunction with a command language, the capitalization and syntax of the choices should be consistent with the command language.
    • Word choices as commands to the computer. 

 Menu Instructions

  • For novice or inexperienced users, provide menu completion instructions.
    • Place the instructions in a position just preceding the part, or parts, of the menu to which they apply.
      • Left-justify the instruction and indent the related menu choice descriptions a minimum of three spaces to the right.
      • Leave a space line, if possible, between the instructions and the related menu choice descriptio
    • Present instructions in a mixed-case font in sentence style.
  • For expert users, make these instructions easy to ignore by:
    • Presenting them in a consistent location.
    • Displaying them in a unique type style and/or color. 

Intent Indicators

  • Cascade indicator:
    • To indicate that selection of an item will lead to a submenu, place a triangle or right-pointing solid arrow following the choice.
    • A cascade indicator must designate every cascaded menu.
  • To a window indicator:
    • For choices that result in displaying a window to collect more information, place an ellipsis (. . .) immediately following the choice.
      • Exception do not use when an action:
        • Causes a warning window to be displayed.
        • May or may not lead to a window.
  • ​​​​​​​Direct action items: — For choices that directly perform an action, no special indicator should be placed on the menu. 

Keyboard Equivalents 

  • To facilitate keyboard selection of a menu choice, each menu item should be assigned a keyboard equivalent mnemonic.
  • The mnemonic should be the first character of the menu item’s description.
    • If duplication exists in first characters, use another character in the duplicated item’s description.
    • Preferably choose the first succeeding consonant.
  • Designate the mnemonic character by underlining it.
  • Use industry-standard keyboard access equivalents when they exist.

Keyboard Accelerators 

  • For frequently used items, provide a keyboard accelerator to facilitate keyboard selection.
  • The accelerator may be one function key or a combination of keys.
    • Function key shortcuts are easier to learn than modifier plus letter shortcuts.
  • Pressing no more than two keys simultaneously is preferred.
    • Do not exceed three simultaneous keystrokes.
  • Use a plus (+) sign to indicate that two or more keys must be pressed at the same time.
  • Accelerators should have some associative value to the item.
  • Identify the keys by their actual key top engraving.
  • If keyboard terminology differences exist, use:
    • The most common keyboard terminology.
    • Terminology contained on the newest PCs.
  • Separate the accelerator from the item description by three spaces.
  • Right-align the key descriptions.
  • Do not use accelerators for:
    • Menu items that have cascaded menus.
    • Pop-up menus. Use industry-standard keyboard accelerators
