We often hear that #commandline is best because it makes you more efficient, you can do SO MUCH more SO MUCH faster than using the dreaded MOUSE!

..... that is, if you can remember all the commands, commandline switches, file locations, etc.
And I think that is true for people like myself who don't use the mouse for its intended purpose like 90% of the time. We are dependent on hotkeys to get anything done, and those hotkeys DO have to be memorized to almost the point of instinctive muscle memory to get productive. In that sense, keyboard users kinda play on hard mode by default
