operations, depending upon the current instrument state. The list is
evaluated from the top, and once a condition is met, its action is
taken and the rest of the list is ignored.

• Increments or decrements a numeric entry menu parameter, either by a

default value, or by one digit place when in digit editing mode.

• Scrolls through available display “pages” or a the displayed table of

measurements and parameters in text mode

if the Trigger menu is selected, pressing ▼will move directly to the Time

need to return to the top of the tree and select the Time menu from there.
