Drop-down combo boxes contain pre-defined entries for the respective fields. In single-select combo boxes, you can select only one entry; in multi-select combo boxes, you can tick a number of entries.
TIP:
Use the Ins-key to select all entries
in a multi-select combo box and use the Del-key to de-select all
entries.
