Build 16212 for Windows 10 PC includes a few interesting internal tidbits that Microsoft appears to be working on. One such thing is a new virtual keyboard, that according to @h0x0d on Twitter, is based on Microsoft's own Swiftkey technology. The new keyboard is part of CShell, and will be available on PC and phones when ready.
Windows Central can confirm that internally the new keyboard features the same swipe typing capabilities on PC that's found on Windows phones today. This makes sense, considering the new keyboard appears to be part of CShell, and therefore is a universal component that will be shared across devices.
Sources also say that the new virtual keyboard will support input via pen too, just like the current Windows 10 PC virtual keyboard. Outside of that, we don't know much else about it. The keyboard is currently in development internally at Microsoft, so hopefully we'll learn more about it over the coming weeks.
One of the most requested features for the virtual keyboard on PC was for Microsoft to introduce swipe support found on Windows phone. Now, it appears that's exactly what's happening. Are you interested in using swipe on a Windows 10 PC or tablet? Let us know in the comments!
