Yhh this is so true and I hate when it happens, one of my biggest pet peeves.
My only thing is some people people genuinley can not type fast enough probably me being one of them - I'd just say abbreviate it xD
well sometimes u barely need to move a couple of joints, then spend 15 of the 20 seconds of reaction time just trying to click on one joint that could potentially save you.
I dont think typing speed would be a problem in such scenarios. These commands would be used to move 1 or 2 joints at max, not to make a whole move with them.
