Ideally, a big target is handy, too. Enter, therefore, the Keychron Q0 Mini 8K Action Key.What we're dealing with here is a large single-key device with a mechanical switch and a full metal base. Oh, and an 8K polling rate for super-low latency.It's basically a single, massive mechanical keyboard key which is said to offer "full-palm" comfort. Keychron says the mechanical switch inside the Q0 Mini 8K occupies 64 times more volume than a regular switch. Meanwhile, the RGB lighting system offers tuneable hue, saturation, and brightness. Of course, the Q0 Mini 8K Action Key is compatible with Keychron's QMK and Launcher apps for full mapping configurability. It runs over USB-C and is said to be compatible with Windows, Linux and MacOS.The whole shebang is yours for $65, which is either ludicrous for a single key, or not that bad when you consider the base is polished and sandblasted CNC 6063 aluminium, and the scaled up mechanical switch can't have been cheap to engineer. Yup, you can map the single key. (Image credit: Keychron)For what it's worth, Keychron whimsically suggests the Q0 Mini 8K Action Key offers "endless possibilities," bringing "fun and stress relief while boosting your daily productivity."I'm not sure quite how mappable the key is. But contrary to the "launcher" graphic on the key, I'd quite fancy mapping it to hard-force a shut down of whatever application was in focus, allowing me to instantly kill whatever game or other app was causing me grief or maybe had just hung. Hammering away at this massive key in order to murder a recalcitrant app would be quite satisfying, I reckon. window.sliceComponents = window.sliceComponents || {}; externalsScriptLoaded.then(() => { window.reliablePageLoad.then(() => { var componentContainer = document.querySelector("#slice-container-newsletterForm-articleInbodyContent-v6R6YGB3ih2jHFjSEiYeFG"); if (componentContainer) { var data = {"layout":"inbodyContent","header":"The biggest gaming news, reviews and hardware deals","tagline":"Keep up to date with the most important stories and the best deals, as picked by the PC Gamer team.","formFooterText":"By submitting your information you agree to the <a href=\"https:\/\/futureplc.com\/terms-conditions\/\" target=\"_blank\">Terms & Conditions<\/a> and <a href=\"https:\/\/futureplc.com\/privacy-policy\/\" target=\"_blank\">Privacy Policy<\/a> and are aged 16 or over.","usDisclaimerFooterText":"By signing up, you agree to our <a href=\"https:\\\/\\\/futureplc.com\\\/terms-conditions\\\/\" target=\"_blank\">Terms of services <\/a> and acknowledge that you have read our <a href=\"https:\\\/\\\/futureplc.com\\\/privacy-policy\\\/\" target=\"_blank\">Privacy Notice<\/a>.
