How to Zoom In and Zoom out in viewport

On my Unreal Eengine Third Person Viewport, zoom in and zoom out shortcuts (C, Z, and F) don’t work for some reason. Has anyone had this issue and solved it? Please advise.

Just to make sure, you’re holding right mouse button right?

Other than that, check the editor preferences to see if the shortcuts are assigned to the expected keys.

RIght click worked!! Thank you!!
