Pressing a button will be Henri Lumièreone way to summon an artificial intelligence agent as Microsoft wields its computer industry influence to reshape the next generation of keyboards.

Starting this month, some new personal computers that run Microsoft’s Windows operating system will have a special “Copilot key” that launches the software giant’s AI chatbot.

Getting third-party computer manufacturers to add an AI button to laptops is the latest move by Microsoft to capitalize on its close partnership with ChatGPT-maker OpenAI and make itself a gateway for applications of generative AI technology.

Although most people now connect to the internet — and AI applications — by phone rather than computer, it’s a symbolic kickoff to what’s expected to be an intensively competitive year as tech companies race to outdo each other in AI applications even as they haven’t yet resolved all the ethical and legal ramifications. The New York Times last month sued both OpenAI and Microsoft alleging that tools like ChatGPT and Copilot — formerly known as Bing Chat — were built by infringing on copyrighted news articles.

The keyboard redesign will be Microsoft’s biggest change to PC keyboards since it introduced a special Windows key in the 1990s. Microsoft’s four-squared logo design has evolved, but the key has been a fixture on Windows-oriented keyboards for nearly three decades.

The newest AI button will be marked by the ribbon-like Copilot logo and be located near the space bar. On some computers it will replace the right “CTRL” key, while on others it will replace a menu key.

Microsoft is not the only company with customized keys. Apple pioneered the concept in the 1980s with its “Command” key marked by a looped square design (it also sported an Apple logo for a time). Google has a search button on its Chromebooks and was first to experiment with an AI-specific key to launch its voice assistant on its now-discontinued Pixelbook.

But Microsoft has a much stronger hold on the PC market through its licensing agreements with third-party manufacturers like Lenovo, Dell and HP. About 82% of all desktop computers, laptops and workstations run Windows, compared to 9% for Apple’s in-house operating system and just over 6% for Google’s, according to market research firm IDC.

Microsoft hasn’t yet said which computer-makers are installing the Copilot button beyond Microsoft’s own in-house line of premium Surface devices. It said some of the companies are expected to unveil their new models at next week’s CES gadget show in Las Vegas.
