The Display Queue page is typically the result of a query produced either from the Welcome page, or the RunOn Sentence. Otherwise the default display is the list of records for which no owner has been assigned. The result is mostly self-explanatory. However there are some parts deserving explanation.
Each of the displayed records is shown in one of three colours. By default, rows alternate between white and pale yellow in an effort to make it easier to distinguish between adjacent row values. The exception is when a row is for a record that is the dependency of another record, i.e. it has a parent. Then the row colour is usually light green. It's configurable, however that's the only colour that's been used.
The queue listing is grouped according to the fields used for sorting. The precision of the sort field specification is used to determine the groupings. Each grouping starts with a heading, showing the values of the sort keys for the group. E.g. if the queue is sorted by the most recent date a record has been worked on, with a precision of "month" (i.e. date_worked-month), then there would be one group per month.
In addition to the sort key values for a group, the headings can contain extra fields. These default to Time Worked and Cost Estimate. The field values for a grouping are summed across the records in the group. So one might see headings like:
Time Worked: 70:30 1w (18 items) Time Worked: 49:25 0w (11 items) Time Worked: 21:05
Note that the "Time Worked" field is the total time worked on the selected items, which includes time spent before the selections. When grouping by a time interval, one often wants to see just the time spent during the intervals, and by a specific person. In such cases, a field history specification is used, so one will instead see:
Time Worked-: 18:10 (32:50 → 51h) 1w (18 items) Time Worked-: 14h (25:10 → 39:10) 0w (11 items) Time Worked-: 4:10 (7:40 → 11:50)
