Choose Your Connection

Software Setup

Custom key functions, layers and RGB settings must be configured through a USB-C wired connection using the current Windows software.

After saving settings to onboard memory, the keyboard can normally retain the configuration when moved to another supported device or when the wireless version changes connection mode.

Mac shortcut note: the current configuration software is for Windows. When preparing shortcuts for macOS, use the Windows key in place of Command and Left Alt in place of Option where applicable. Shortcut behavior can vary by application and operating system.
