Table 7-2 lists the vertical modes with their corresponding controls and annunciations. The mode reference is

The NOSE UP/DN Wheel can be used to change the vertical mode reference while operating under Pitch Hold,
Vertical Speed, or Flight Level Change Mode. Increments of change and acceptable ranges of values for each of
these references using the NOSE UP/DN Wheel are also listed in the table.
