Smart Backlighting
The keyboard features an embedded ambient light sensor that reads and adjusts the backlight brightness accordingly.
Backlighting Levels Based on Room Brightness:
| Room Brightness | Backlight Level (Dark Keyboard) | Backlight Level (Light Gray Keyboard) |
|---|---|---|
| Low light - Below 100 lux | L2 - 25% | L4 - 50% |
| Medium light - 100 to 200 lux | L4 - 50% | L4 - 50% |
| Bright light - Above 200 lux | L0 - No backlight* | L0 - No backlight* |
*Backlight is turned off.
The backlight has seven levels.

| Bright light - Above 55 lux | L0 - No backlight* |
*Backlight is turned off.
Backlighting Behavior and Notifications
The keyboard's backlight behavior is optimized for user experience and battery saving.
- Bright Environment: When the ambient light is too bright, the keyboard automatically disables the backlight to avoid unnecessary use. This also conserves battery, allowing for longer backlight usage in low-light conditions. You will see a notification if you try to turn on the backlight in such conditions.
- Low Battery: When the keyboard has 10% battery remaining, the backlight will turn off, and a battery notification will appear on the screen.
F-Key Toggle
Press the [Fn] + [Esc] keys to toggle between Media Keys and F-Keys. A notification will appear to indicate the switch status.
Note: By default, the keyboard functions as Media Keys.
Logitech Flow
You can use the MX Keys S keyboard to work across multiple computers. When paired with a Logitech mouse that supports Flow, such as the MX Master 3S, you can operate and type on multiple computers using the same mouse and keyboard setup via Logitech Flow technology.
You can move your mouse cursor from one computer to another. The MX Keys S keyboard will follow the mouse and switch computers simultaneously. You can even copy and paste between computers. You need to install the Logitech Options+ software on both computers and follow the instructions here.
