Help - Right-click with new pen

Hi, @thhm. Welcome to the forum.

You should go to Settings, Pen & Windows Ink. There you will find options for the pen.

I have the Surface Pen with no clip. You may have a different pen. Refer here: https://support.microsoft.com/en-us/help/4036281/surface-how-to-use-your-surface-pen

On my settings screen (see screenshot), the main pen button (on the butt end) can be configured to do different functions, depending upon whether you click one, twice, or long-click.

Right-click with Side Button
Obviously, to left-click with the pen, you tap the screen. But to right-click with the pen side button, you press the button, then tap the screen.

Just like the pen left-click cannot be altered, the right-click function is not normally programmable.

Give this a try and let us know.
