I live on the command line. Between vim, tmux, and xmonad, there isn't much I have to use the mouse for these days. Given my love for keyboard navigation, it only makes sense that I learn as many of the command line shortcuts available as possible. Here I detail some of the most helpful navigation tricks, and those I use on a daily basis.
As a developer, I tend to prefer automation whenever possible. Hours of your life are lost in the minutes spent doing that which could easily be scripted. The classic rule of thumb I try to follow is "if you have to do it twice, automate it."
