2.7.6-9 Feedback for Mode Selection

When the result of user actions will be contingent upon prior selection among differently defined modes of interaction, a continuous indication of the current mode should be provided, particularly when user inputs in that mode might result in data loss.

Additional Information:
A user cannot be relied upon to remember prior actions. Thus, any action whose results are contingent upon previous actions can represent a potential threat to data protection. For example, if a DELETE mode is being used to edit displayed data, some indication of that mode should be continuously displayed to the user.
