I have not tried that yet, no. For me the goal isn't just about shortening often repeated commands, as though the limitation were purely about character input speed, it's more of a contemplative practise of learning how to notice and respond to that internal prompt that says "I wish I could say that more succinctly" or "There has to be a better way to do this". And then either telling my mind work on those questions, or being open and receptive to coming across something relevant on the topic, or seizing a moment of inspiration to write a time-saving script or come up with a meaningful (to me) alias.
