Three different combo-boxes are displayed below. \
|
|
You can add characters to the first \
|
|
one by pointing, clicking and typing, just as with an entry; pressing \
|
|
Return will cause the current value to be added to the list that is \
|
|
selectable from the drop-down list, and you can choose other values \
|
|
by pressing the Down key, using the arrow keys to pick another one, \
|
|
and pressing Return again. The second combo-box is fixed to a \
|
|
particular value, and cannot be modified at all. The third one only \
|
|
allows you to select values from its drop-down list of Australian \
|
|
cities.
