There are many tools that can help you position and arrange items
on a page. The information on the following pages will describe how
to change build order, display and change the size of bounding boxes
and changing the tab order.
Displaying bounding boxes
Each item on the form has an invisible bounding box around it. Bounding boxes include all the elements of the item such as built-in labels and borders.
Changing the build order of items
As you place items on the page, they form a sequence. This sequence is called the build order, since it is the order in which you build the form. This means items later in the build order are drawn before (in front) of items earlier in the build order.
Tab order
Tab order is the order in which the user can move from one item to another item on a page using the Tab key. Filling in a form is much faster and easier if the user only has to press Tab to jump to the next item in a logical sequence.
