In any panel, on any column where sorting makes sense, you can sort records on that column by clicking the header, once for sorting in one direction, once more to switch directions. The fact that records are sorted on that column, as well as the sort direction, is shown by an arrowhead next to the column caption.
You can sort on several columns in succession. Hold down the Shift key. The first column you click will be the first sort key, the second will be the second key, and so on. Re-click on any column without Shift, and it becomes the single sort key again.
The context menu of some AQTime panels offers Sort Ascending and Sort Descending. This is another way of doing what a simple click or two would do.
To cancel sorting on a column, press the Ctrl key and then click the header of the appropriate column.
