Form Tabbing Confusion

After opening the Tab Editor you will see a screen like this:

To select the order of tabbing simply label the form controls in order. If the user’s mouse is in form control number 1 in the tab editor, then when the user clicks tab it will go to form control 2 and so on. The numbers are originally given based on the order that form controls are placed in the form. But to configure it how you want, you do that through the tab editor.
