MEP 2015(?) used to have a scroll wheel that you could click on and with the mouses scroll wheel you could frame by frame that way.
In MEP 2020 there's no wheel so I have to hammer away at the keyboard arrows which can be quite annoying especially on the fingers. Is there a way to use the mouse own scroll wheel to form this, or has this function not in the program, if it isn't could someone recommend returning it in the next version of MEP.
