Microsoft has announced the biggest change to its keyboards in three decades with the introduction of an artificial intelligence (AI) key, Paralel.Az reports citing BBC.

The key will allow users to access Copilot, Microsoft's AI tool, on new Windows 11 PCs.

Microsoft is a major investor in OpenAI, which powers Copilot's AI capabilities. It integrated AI into other products such as Microsoft 365 and Bing search in 2023. Rival Apple has included a Siri button or option on its touch bar in Macbooks for a few years.

Copilot helps users with functions such as searching, writing emails and creating images. In a blog announcing the change, Microsoft executive vice president Yusuf Mehdi said it was a "transformative" moment and compared it to the addition of the Windows key nearly 30 years ago.

He added that it would "simplify" and "amplify" user experience.

The new keyboards are expected to be on new products from February.
