Some functionality in SEER*Stat results matrices operates on the highlighted column or row. To highlight a row or column, follow these steps:
Move the mouse cursor to the topmost column header or leftmost row header. It will change to an arrow, pointing towards the cells in the column or row.
To select only that column or row, left-click once. The background will change color to indicate that it is highlighted. To select multiple columns or rows starting with that one, left-click and drag the mouse cursor across the desired columns or rows until all are highlighted.
At this point, you can right-click inside the highlighted header(s) to access the right mouse button menu.
