Is the bottom/left, second key in horizontally, the same as the Windows key?
Asked by: John
The Windows key on the Logitech MX Keys S Wireless Keyboard (Black), B&H # LOMXKSB, is labeled as "Start / Option." When using it with a Mac, it would work as the option key; when working with a PC, it would function as the Windows key.

Hi, is it compatible with any mice in the logictech M series?
Asked by: Deep
The Logitech MX Keys S Wireless Keyboard would connect to your computer independently of other peripherals, so there would not be any compatibility problems with a mouse. If you have a Logitech mouse which supports the Logi Bolt receiver, then both devices could use the same USB receiver. Otherwise, there would normally be no interaction between your keyboard and mouse.

Can the Logi Bolt receiver be connected thru a USB-C to USB-A hub? Will this cause increased latency or dropouts?
Asked by: George
The Logitech Logi Bolt USB Receiver (BH #LOBLTRCVMXKM), included in the Logitech MX Keys S Wireless Keyboard & Mouse Combo Kit (Black), can be connected to a hub, but for the best operational experience we recommend connecting directly to your computer's USB input.

If a hub doesn't work well, can the Logi Bolt receiver be used reliably with a laptop that has only 1 USB-C port for I/O?
Asked by: George
The Logitech Logi Bolt USB Receiver (BH #LOBLTRCVMXKM), which is included in the Logitech MX Keys S Wireless Keyboard & Mouse Combo Kit (Black), uses a USB-A connection, so it will not be able to plug directly into a USB-C port. You could use a USB adapter like the Pearstone USB 3.2 Gen 1 Type-A Female to USB Type-C Male Adapter (BH #PEAAFCM) to adapt the Logi Bolt to your computer's USB-C input.

Can this be connected with and powered by a USB cable?
Asked by: Jeff
Note: the answer from the Logitech rep that mentions connecting "via Bluetooth or the INCLUDED Logi Bolt USB receiver only applies to the keyboard/mouse kits. This item does not include the Logi Bolt USB receiver when purchased as keyboard only. The box states "Compatible with Logi Bolt USB receiver (not included)".
