# input focus

At run time, an object in a graphic display has input focus when it is active and ready to receive input from the mouse or keyboard. Some objects need to be selected by tabbing to them, pressing them (on touch screens), or clicking with the mouse to activate them.

Press the Tab key to move to the next object that accepts input focus. The order in which Tab moves between these objects is from upper left to lower right.

Press Shift+Tab to move back to the previous object that accepts input focus.

Objects that accept input focus include the trend object, the control list selector, the piloted control list selector, the display list selector, the alarm list, alarm status list, and alarm banner, the diagnostics list, the numeric input cursor point, and third party ActiveX controls.
