this is really REALLY simple

the mouse has a function that allows you to write your own "custom macros" the choices for binding it gives you tie in to the "DEFAULT keybind letters" of the DEFAULT wow settings. this didnt work for me either, it fucked EVERYTHING i had up lol.

Here's what you do:
1. Open the macro thinger on the bottom right
2. Select "New"
3. Create a ONE BUTTON PRESS macro, i use the right half of my numbers since i dont use them with my normal play, ie buttons 6 7 8 9 0 - and = and after you have selected the key, just press it once and let it go, select the "NO delay button" so that it counts as a quick instant press.
4. Click OK to Save the macro and then assign it to a button somewhere on the mouse, then you're done
