Things to learn through repetition.

CLI/UI Navigation (vim / tmux / i3)

Vim, tmux and i3 all have similar concepts. You can have multiple things on screen, each can be maximized, and you can also have collections of those things offscreen. This is an over simplification. We're not going to get into things like vim buffers, tmux sessions, and i3 containers. Let's keep it simple.

Tool Things on screen Off screen
vim windows tabs
tmux panes windows
i3 windows workspaces

If I'm in i3, I'm usually local to the machine and don't start tmux sessions. So for me it's either ssh+tmux+vim+entr, or i3+vim+entr.

These are the everyday things I have to do in each:
