Command-BuildingGuidelines

• Match commands to meaning
• Use words the user sees on the screen when
  possible
• Balance ease of saying and ease of remembering
• Keep commands succinct
• Dont use synonyms
• Conserve words by using multiple meanings

No synonyms in theHuman-machine dictionary

• "This" is the only word that refers to something
  that is highlighted or on the clipboard.
• e.g. "This Cut", or "This Bold"
• "Back and Forward are the only words that
  refer to moving a selection
• e.g. "Word Back 3" moves the word nearest the
  cursor 3 words to the left.

Conserve words by using more than one
meaning Top

• The word Top has two meanings in the Renji
  dictionary
• The beginning of a document e.g. Go Top
• The top half of a paragraph or document e.g.
  Graph Top
