2.2.3-7 Consistent Functions in Different Operational Modes

When a function key performs different functions in different operational modes, equivalent or similar functions should be assigned to the same key.

Additional Information:
Functions assigned to a given key in different modes should be related. For example, a particular key might be used to confirm data changes in one mode, and confirm message transmission in another. As a negative example, a key labeled RESET should not be used to save data in one mode, dump data in another, and signal task completion in a third.
