+1, not having to use a mouse is great. I also use zsh's inbuilt git aliases [0] which I can't recommend enough -- I've found using git CLI without them a pain now that I'm used to them. These together have me productive and happy.
Tip for new tig-players: whilst you can use tig perfectly fine with just the keyboard, it does support using the mouse. Just add `set mouse = yes` to `~/.tigrc` :)
