What do the TabIndex values determine for the controls of an interface? What is the standard tab order for controls on an interface?

What will be an ideal response?

The TabIndex values determine the tab order of the controls, which is the order in which each control receives the focus when the user either presses the Tab key or employs an access key while an application is running. The TabIndex values begin with zero, and each subsequent control will receive the focus based on its TabIndex value. The standard tab order for controls of an interface is determined by whether or not a control accepts user input. Any control that accepts user input should be first; all other controls follow. If a control that accepts user input is identified by a label control, you include the label control first and then its related control.
