What are cool bindings for left mouse button?

Hey everyone, Im just curious if anyone has any interesting ideas for left mouse button bindings. I think the most common one is attack move on left click but Ive also seen cool things like drag scroll on left click which allows for unique camera control. Overall, I want to use my LMB for a function beyond just using it in the shop etc. I actually tried binding my ping wheel to LMB but it did cause some issues when moving my camera around on the map. Let me know if you use your LMB for a binding and id be interested to try it out
