In case of binding aim or shoot for other buttons than left/right mouse click, it doesn't shoot/aim whatever bind it is. tested on MacBook Pro M1, Minecraft 1.20.1, mod version 1.102-release.jar
It's impossible to have left and right clicks be done simultaneously, as RightMouseClick is two fingers click over trackpad, and LeftMouseClick is one finger click, so RMC and LMC are impossible to be done simultaneously (either shoot or aim). I just wanted to bind it for example for tab or "`" (on my layout it's over tab). In Minecraft it binds. but does not work on practice. help!
I hope it's an easy fix!

happens only on manual/semi modes. auto works well
