Solaar/docs/devices.md

Solaar will detect all devices paired with your Unifying Receiver, and at the very least display some basic information about them.

For some devices, extra settings (usually not available through the standard Linux system configuration) are supported:

• The K750 Solar Keyboard is also queried for its solar charge status. Pressing the Solar key on the keyboard will pop-up the application window and display the current lighting value (Lux) as reported by the keyboard, similar to Logitech's Solar.app for Windows.

• The state of the FN key can be toggled on some keyboards (K750, K800 and K360). It changes the way the function keys (F1..F12) work, i.e. whether holding FN while pressing the function keys will generate the standard Fx keycodes or the special function (yellow icons) keycodes.

• The DPI can be changed on the Performance MX Mouse.

• Smooth scrolling (higher sensitivity on vertical scrolling with the wheel) can be toggled on the M705 Marathon Mouse.
