The field names used by the database are often short and cryptic so you can customize what you would like to be displayed as the field name here. Click on any field name and enter the text you would like to be used as its label.
Choose Tool tips:
Tool tips are little windows with special instructions that will open to the end user when they hover over the field name. This is useful if the title you give your field name is not descriptive enough and you need to impart some more detailed instructions on how to fill out the field. By default the instructions you type will be used on the both the add form and the edit detail form. Because the search form will usually involve a different set of instructions for the end user you can simply choose this additional formatting by selecting "Tool tips add/edit" or "Tool tips search".
