ChromeOS users can already access a lot of Android games through Google Play, but many of them are made with a touchscreen interface in mind. That can make it difficult for users to play these titles using a keyboard and a mouse. To solve this problem, Google today announced that with ChromeOS 105, it’s testing keyboard controls for select titles.

The company said that it’s simulating touch controls through keyboard presses to map touchscreen controls to a desktop system. It also insisted that developers should implement keyboard controls in their games so they would work better on Chromebooks without a touchscreen.
