Taskbar – In Windows the taskbar stretches across the bottom of your display, or it could be on the side of the display depending on its setting. It includes the clock and electronic buttons that represent your open applications.  If the taskbar ever disappears from view for some reason, hold down a CTRL key and press ESC at the same time to make it reappear.  Another way to pop back and forth among open programs is to hold down the ALT key and at the same time press the TAB key.
