An empty field normally indicates that a name or number is to be entered. Click within the field in question and use the keyboard to enter a number or desired text. In order to change an existing entry, double-click the entry to be overwritten. The field then becomes blue and can either be overwritten directly or the existing text can be deleted using the delete/backspace key.
	For functions that offer more than just being switched on and off but only have a few options to choose from, the field already contains a default setting. To change this, click the opened list field to make a selection. • If this is a single field with an arrow pointing downward, open the list field by clicking the field. • If there are multiple fields in a table column (without an arrow pointing downward), open the list field by double-clicking the field.
	For some functions, a small circular button (radio button) is located next to the setting options listed. The selected setting is indicated by a black dot inside the circle. The setting is changed by clicking an empty circle. Selecting this setting option simultaneously deactivates any other previous selection.
	A square check box indicates a switching function. An empty check box means "off" and "no"; a check mark on the other hand, means "on" and "yes". The switchover is done by simply clicking the box.
