The text heading of the column(s) that the Event List is sorted by are highlighted in blue. By default, the Event List is sorted by date and time so events are listed in order of occurrence. The Event List can be sorted by a different column by selecting the column heading with your mouse. Also, the event list can be sorted by several columns at once by selecting menu items in the Sort menu. Sorting by multiple columns helps to group events so that events can be in a specific order.
