I had an ... issue ... in my right hand that kinda forced me to become left handed, at least when controling something that requires a lot of continous repetitive movement like clicking ..... I am not only left handed but I use a mouse that looks a lot more lika a joystick, in which the "left button" is activated by my thumb lol .... nevertheless "accommodate", in my case at least, is just adding JIKL be the same as AWSD, then the shift could as well be H or space, space is better
