The operator name field allows you to select operators or procedures by entering (part of) their name. After pressing Return or pressing the button of the combo box, the system is looking for all operators or procedures that contain the entered name. The order of the listed result is as follows: Operators and procedures whose names begin with the given substring are listed first, followed by all operators and procedures that contain the substring elsewhere. Both parts of the list are sorted in alphabetical order.
If there is an unambiguous search result, the parameters are displayed immediately in the operator window. If there are several matching results, a combo box opens and displays all operators or procedures containing the specified substring. By clicking the left mouse button you select one operator and the combo box disappears. Now, the operator's parameters are shown in the operator window.
The short description of the selected operator is displayed in the status bar. The operator name is displayed in the window title of the operator window.
