To Build a Key-in

In the left-most list box of the Key-in window, select a keyword.
The selected keyword is displayed in the key-in field, and subordinate second-level keywords are shown in the Key-in window's next list box.
As necessary, select additional keywords, one per list box from left to right, until the desired key-in is constructed.
To enter (submit) the constructed key-in, click the Run Key-in icon or press <Enter>.
