Chrome on Windows is getting a feature Edge doesn’t currently support: the use of its hardware media keys. Google Chrome Engineer Becca Hughes announced on chromium.org that Chrome 73 will be adding support for Media Session API in Windows and Chrome OS. In theory, this means you can control sites like YouTube using the hardware keys available on some keyboards as well as possibly Windows 10 pop-up media bar. This feature isn’t currently available to Edge, but Microsoft’s browser should get it too once it switches its rendering engine to Chromium.
