In modules with graphical structure display, the records are displayed in boxes. Each box contains object data and can contain additional control elements for moving, inserting, marking and deleting, depending on the requirements.
Moving can be done via the bar at the left margin of the box.
There are certain symbols for inserting, marking and deleting at the lower right margin of the box.
If one of the two parameters is activated, all control symbols are displayed but only the active parameter is displayed as active (colored) while the other parameters are displayed as inactive (gray).
If both parameters are activated, the third element (marking) is also available via the corresponding symbol.
The standard marking function (CTRL + mouse click) is generally allowed
