2.2.3-8 Logical Pairing of Chord-Keyed Functions

If chord-keying is used, the functions paired on one key should be logically related.

Additional Information:
Functions assigned to a given key should be related. For example, if a particular function key moves the cursor to the upper left corner of a display screen, then that same key when shifted might be used to move the cursor to the bottom right corner of the screen. As a negative example, a function key that moves the cursor should not be used when shifted to delete displayed data.
