A:Answer This keyboard only has a "caps lock" indicator located near the power switch.
The SetPoint software for Logitech devices offers an on-screen overlay indication of all three lockables: caps-lock, num-lock, scroll-lock. As you tap one it shows the state it was changed to. Caps-lock presents either an A or a "Slash-A" to show caps on or off, number lock with a "1" or "Slash-1", and scroll-lock with (arrow) or "Slash-Arrow"
