If you are attempting to farm clickable items such as Onyx Eggs, Dark Soil, Padaria artifacts, etc, then you will have a hard time searching for the items. There is an easier way to farm these items using a method and possibly a tool, which will change the environment to just show those items. You can also use this to see rare NPCs, Spawn Points, or to look down through a dungeon to a certain spot.
As a method, you can quickly switch back and forth between two different macros which are shown below. This method is the more difficult way to do it, because you need to do it yourself, however it’s also a bit less likely to cause you issues down the line. The second way, uses a custom made addon to do the same thing, but if good ol’Blizzard has a way to detect addons, might be able to tell you’re using this cheat method. Of course it’s really hard to prove, since you aren’t accessing memory in either case so it’s a hard thing to prove in any case.
