iPhone Mirroring Scrolling Horizontally

[basher]

Can anyone tell me how to scroll horizontally in iPhone mirroring when using a non-magic mouse on the Mac? I'm trying to scroll through watch faces in the Face Gallery of the iOS watch app.

Scrolling horizontally works fine with the Magic Trackpad.

Had the same question, hold down shift and it'll be a sideways scroll.

Thanks for that. Perfect solution!
