Setting Up the Logitech MX Keys Mini
Most people skip the manual entirely and just pair the keyboard, which works fine for basic use. But if you want to actually use the device properly, the Logitech MX Keys Mini Manual covers things that aren't obvious from unboxing alone. The main thing everyone misses is that this keyboard has three distinct connection modes and you can't switch between them without running the Logitech Options+ software on your machine. Pair it via Bluetooth and you lose the ability to remap keys, adjust function layer behavior, or sync it with a mouse in Flow mode. You can find the full PDF at logitech.com/en-us/products/keyboards/mx-keys-mini.html under the support or resources section. It's roughly 4.2 megabytes and covers everything from key travel distance to how the smart illumination actually decides when your hands are near the board. The download link isn't always obvious because Logitech buries it under tabs labeled "Support," then "Downloads," then "Manuals." If you don't feel like hunting through their site, you can also search "MX Keys Mini User Guide PDF" and hit the official PDF directly. I ran into a specific issue a few months ago that the manual barely addresses. After updating my Mac to a newer version of macOS, the keyboard's multi-device switching stopped working. Pressing the FN+1, 2, or 3 keys would register the LED change but the input wouldn't actually shift to that paired device. The manual says to unpair and re-pair, which I tried three times with no improvement. What actually fixed it was running the Logitech Options+ app, going into the device settings for the MX Keys Mini, and toggling the "Enable Logi Options+" setting off and back on. The firmware had quietly updated in the background after the macOS install and the old pairing handshake was broken. This isn't documented anywhere in the manual. You have to stumble into it.
The keyboard uses a low-profile scissor-switch mechanism with 1.5 millimeters of key travel. That's shallower than the full-size MX Keys which sit at 2 millimeters, and it matters if you're coming from a mechanical keyboard. Typing accuracy drops noticeably during the first week because your muscle memory is aiming for a bottoming-out feel that this board doesn't provide. Most people think it's a defect or a faulty key. It isn't. I had a support ticket drafted for my second unit before I realized I was pressing hard enough to make the laptop underneath the board rattle. Lighter touches solve this entirely. The smart illumination on this keyboard has a known quirk. The ambient light sensor sits between the F-row and the number row, slightly left of center. If you place a monitor stand or a tall notebook directly in front of the keyboard, the sensor reads darkness and the backlight stays at maximum brightness even in a well-lit room. The workaround is to angle the board slightly downward so the sensor faces the room rather than the obstruction. This costs you nothing and fixes what looks like a malfunction. The manual mentions the sensor location but doesn't warn about this setup problem. Multi-device switching uses Logitech's Flow technology when paired with a compatible Logitech mouse on the same network. This lets you move your cursor off the edge of one screen and it appears on the other, with clipboard sharing between devices. The catch is that Flow requires both devices to be on the same local Wi-Fi network and both to have Options+ installed. If one machine is connected via Ethernet and the other via Wi-Fi, or if a firewall blocks mDNS discovery, Flow silently fails. The keyboard will still pair to both devices and the LED indicators will show connections, but the cursor handoff never happens. Check your network configuration first before assuming the keyboard is broken.
Battery life is rated at 10 days with illumination on and 5 months with it off. These numbers assume 4 hours of active use per day. If you're charging nightly like most people do, the 10-day rating is realistic. If you leave illumination at maximum brightness in a dark room, expect closer to 5 days. USB-C charging is supported and a 5-minute quick charge gives you about 3 hours of use, which is enough to survive a long flight or a full workday if you forget to plug it in overnight. The function key layer is another area where the manual could be clearer. By default, the top row acts as media controls. You hold FN to access the secondary functions like volume sliders and playback controls. There's a setting in Options+ to reverse this so the top row is F1-F12 by default with media controls on the secondary layer. This is useful if you write scripts or use terminal shortcuts regularly. The manual mentions this toggle exists but doesn't explain which professions benefit from flipping it, so most people leave it in the default media configuration. If you're deciding between the MX Keys Mini and the full-size MX Keys, the main tradeoff is the numpad and the dedicated row for emoji and special characters. The Mini cuts those to save desk space and weight. The keys themselves feel identical. The keycap texture, the slight concave shape, the quietness of the switches - nothing changes between the two models except layout. Price difference is usually around $40 to $50 depending on the retailer. The Mini is the better buy if you don't type numbers frequently. The full-size model is worth it if you work in spreadsheets or accounting.

The keyboard supports both Bluetooth 5.0 and the Logitech Unifying receiver. You can use both simultaneously, which means one device can connect wirelessly while another uses the USB dongle. This is useful in hybrid setups where one computer is desktop-grade and another is an older machine without Bluetooth built in. The manual covers this briefly in the connectivity section but doesn't explain the practical value. Most users only connect one device at a time and never discover this capability. There's also a known issue with the bottom silicone feet on early production runs. After about 8 months of use, the feet can degrade and become tacky, especially in warmer environments. This causes the keyboard to slide slightly when you type aggressively. The fix is to wipe the bottoms with isopropyl alcohol and let them dry completely. If that doesn't restore grip, you can purchase replacement feet from third-party sellers on Amazon or eBay for about $6. Logitech doesn't sell replacement feet officially, which is a gap in their support documentation. Overall, the MX Keys Mini is a solid keyboard for its category. It's not perfect. The sensor placement issue, the Flow reliability problems on mixed networks, and the early production feet degradation are real limitations. But for someone who types a lot and values a compact layout with good battery life, it does the job well. Just run the firmware update through Options+ within the first week of ownership. That alone resolves most of the issues people report online.
