A:Answer Hello, The only mouse/keyboard combo with a caps and numbers lock indicators would be the MK710. However, it is indicated on the LED display of the keyboard and not on the keys themselves. The MK270, MK520, MK540, and MK850 have and LED indicator light on its CAPS lock key. If you install Logitech's Options software, an on-screen notification will come up when you press CAPS lock or Number lock keys.
