Maus Makro?

Is it possible to put a GS macro on the mouse wheel? if yes how?

while you are ingame type /kb than select empty ability slot on ur bar and do a scroll down or up to keybind it. make sure you go to ur wow keybinds and under camera switch ur zoom in and out as it is default to zoom out and in on mouse scroll.
1* /kb
2* assign it to slot
3* make sure u remove the default assign

4* Enjoy and you are welcome
