6. Remap keys
We don't have an official software to remap the keys yet. But you can use these two
software to get the job done. (Expect the light effect key.)
For Windows - SharpKeys
For Mac - Karabiner
6.5 Linux Setting
We have a Linux user group on Facebook. Please search "Keychron Linux Group" on
Facebook. So you can better experience with our keyboard.
7. Turn Off the Backlight
If you are on the Mac, the default is to press F5 key. If you are on the Windows, the
default is to press fn + F5 key.
