One of the final tasks to do when creating a form is to set the tabbing order. Before you do this task, make sure you have finished laying out the form design so that all the objects are in their correct position on the form. First, you should examine the default tabbing order, which is created automatically by LiveCycle Designer ES.
When you design or open a form in LiveCycle Designer ES, the tabbing order is not visible. To see the tabbing order for the form, select View > Show Tab Order or click Show Order on the Tab Order palette.

Examine the default tabbing order carefully to determine whether it suits your particular requirements or whether you need to change it. Even if you modify the tabbing order, you can quickly return to the default tabbing order by selecting the Automatic option in the Tab Order palette.
