I know we used to be able to bind multiple actions to one key. It changed around the time emotes and free wards came out because at that time I set wards and emotes both to T and I still have that set today - whenever I put a ward down I also cast an emote. But I am no longer able to bind any other keys to the same button.
Specifically, Foggedftw taught me Trynd's swag spin where if you spin and use laugh, the character portrait stands still while effectively I would still be spinning. I find pressing E and then control+3 quite tiresome after a long time. I currently changed laugh to Y since I pretty much never use character focus camera anyway. But I am wondering if there is still valid options out there that can just let me bind laugh to E so I can spin and laugh.
