You saved one keypress on the e but added at least two on the capital letters
Tesla and TSLA both require six keystrokes.
If you’re trading then TSLA is far more natural.
If you're using the shift key, then "Tesla" is 6 keypresses whereas "TSLA" is only 4.5 (.5 since you don't technically have to release shift, which you can take advantage of in certain cases [0]).
You took 79 key presses to point that out. And here I am taking even more to respond. Clearly commenting is not based purely on a keypress-based economical model.
