Access or minimize your quick-start apps without using the mouse
Use the combo [window key] + [1] to [9] to activate or minimize the corresponding programs from your taskbar. Use the numeric keys on the top of the keyboard. As you can see in this small demo, while the mouse is in the middle of the screen, pressing win+2 windows explorer starts which is the 2nd icon. By pressing win+2 again it gets minimized.
