  • KN.13 All keyboard-invoked menus, windows and tooltips appear near the object they relate to.
• MI Mouse Interaction

  • MI.2 All mouse operations can be cancelled before they are complete.
  • MI.3 Visual feedback is provided throughout drag and drop operations
  • MI.4 The mouse pointer is never warped under application control, or its movement restricted to part of the screen by the application.

  • FT.8 An alternative to WYSIWYG is provided. For example, the ability to specify different screen and printer fonts in a text editor.
• CC Color and Contrast
  • CC.1 Application colors are not hard-coded, but are drawn either from the current desktop theme or an application setting.
