Lenovo Go Wireless Split Keyboard AI

The Lenovo Go Wireless Split Keyboard AI is a new wireless keyboard built for US English typists. Its split layout encourages a more natural hand position during long sessions. The 88 key design keeps the footprint compact while retaining essential functions. Windows 10 and Windows 11 compatibility is confirmed by the manufacturer.

Wireless RF connectivity with USB Type A receiver

A 2.40 GHz RF link connects the keyboard to a host via a standard USB Type A dongle. No Bluetooth pairing steps are required for basic operation. The split halves remain tethered together by a flexible cable for unified placement. Build materials follow Lenovo commercial accessory standards for daily office use.

Dedicated CoPilot hot key for AI assistance

A specific CoPilot hot key launches Microsoft AI features instantly on supported Windows 10 and 11 systems. This single key defines the keyboard's primary differentiation from standard split models. Buyers who do not use Copilot or need a numeric keypad should consider other layouts. The part number is 4Y41R64755.
