As you click each part of the attribute or operation, the label for that part appears in bold type in the combo box. If applicable, the selected part of the operation or attribute has a drop-down list of values.
For example:
1. Double-click the stationID attribute in the EntryStation class.
2. Click the word private. Notice that the word visibility appears in bold type.
3. Press CTRL + down arrow. A drop-down list opens that displays values that you can select for the visibility attribute.
4. Select a new value from the drop-down list and press Enter.
The attribute is updated with the new value.
Note: You can also type a new value directly in the editor. If you do not see what you need in the drop-down list, use the right and left arrow keys to position your cursor and type the appropriate value.
5. For this tutorial, use the value private and press Enter to close the editor.
