This is to describe how to change the value of a field of a form from it's default when it is clicked on so that it auto-clears and changes to how it normally works.
Note the value in the below field. Now click on it and it disappears, allowing you to type normally. Clear whatever you type so the field is empty and click somewhere on the page (not on a link as this will take you to another page) and the field returns to displaying "Name:".
Thank You! :c)
