When you install and open the Microsoft Mouse and Keyboard Centre software, the supported Microsoft mice and keyboards connected to your computer are automatically detected and displayed. If you add a new supported device or disconnect an existing one, the device images displayed in the UI are automatically updated.
The app-specific settings available to you in the Microsoft Mouse and Keyboard Centre software are based on the specific device model you select.
You can assign buttons/keys to perform different commands in different programs. For example, you can assign the same button/key to activate Digital Ink when in PowerPoint, a macro when in a game, and the Magnifier when in any other application.
