To customize how your Arc Touch Mouse works with Surface, download the Arc Touch Mouse Surface Edition Settings app. Here’s how:
- From the Start screen, tap or click Store.
- Make sure you’re signed in with your Microsoft account.
- In the search box, enter Arc Touch Mouse Surface Edition Settings.
- Tap or click the tile for the app, then tap or click Install.
Also, if you want to reassign mouse button to perform common tasks quickly and become productive, you may download our
Microsoft Mouse and Keyboard Center.
Let us know if this help with your concern,
