Suppose you want to remove the repeatable item, STARTYEAR, from
the previous GROUP BY clause:
- Move the cursor to the repeatable item, STARTYEAR
- Press Enter to make STARTYEAR the current repeatable item. Its
color changes from yellow to green.
- Move the cursor to the groupingexpr fragment.
- Press the Deselect function key (F4). The repeatable item, STARTYEAR
(and its preceding repeat separator), is deleted from the GROUP BY
clause.
