1. From View menu select "Tab order". Tab orders for all form elements will appear.
2. Click on EACH element in order, that you want, only one time per element (i.e. click on element, which you want to have tab order 1, then on element which you want to have tab order 2 and so on). DO NOT CLICK ON ELEMENTS IN DIFFERENT ORDER, NOR RETURN BACK TO ELEMENT, ON WHICH YOU ARE ALREADY CLICKED!!!
