Viewing and Navigation encompasses the wide variety of behaviors and operations that allow users to view content, navigate the interface and perform actions on application content.

Viewing content

• Viewing vs Editing - Do not use input controls for content that is primarily viewed.
• Images - Preserve the characteristics of images that convey emotion and meaning.
• Icons and text - Consistently show icons with text.
• List view - Use a list view to show some items out of one category.
• Tree view - Use a tree view to show items with a single, natural, hierarchical categorization.
• Grouping
  • Groupbox - Arrange associated controls by using a labeled group box or an unlabeled frame.
  • Splitter - Allow users to resize aligned groups by placing a splitter between the groups.
  • Tabs - Use tabs to show related information on separate pages.
• Tooltips - Consistently present tooltip information.
• Search and Filter - Guidelines for exposing search and filter functions
• Wizard - How to guide the user through a series of step to accomplish a task
