Invert movement in editor?

Hi,

When moving the camera in the editor, I've noticed that using the middle mouse button to move the camera behaves backwards from what I'm used to in other editors? Is there a way to invert the camera movement, but only for movement. The looking feature when pressing the right mouse button works like I expect.

Basically, I'm used to the camera moving right when I move the mouse right. Instead the camera moves left. Same inversion is true for up/down movement.

I've looked in the edit menu under preferences and project settings->input, but I haven't had any luck finding a fix for my problem.

Thanks, Brian
