Ever look at someone the wrong way? I have, and by looking the wrong way I mean typing k instead of l. Now I often try my best not to make mistakes but I'm not perfect and it does happen but the one thing I could always count on was the fact that I could never unintentually murder a player char because the murder command must be typed out in full to do so to initiate a murder. What about applying this to the kill command? instead of just half typing out the word or a single letter you would have to type out the word in full or set an alias to do it for you. what I tried for a while was to set the k key to do something else when I accidentally hit in in connection to a mob, this is good but I honestly think if the full typing was required there would be less accidents to worry about.
Thanks for hearing me out
