Tmux/screen foreign concepts
I remember being a young intern and a senior dev taught me about screen. It was cool and I immediately forgot how to use it.
Every time I use screen I forget how it works. Doesn't matter if it was an hour ago I forgot either how to detach, or how to reattach.
I've been using byobu, which is a wrapper. No idea how actual screen or tmux work, but in byobu it's just F2 for a new screen, F3 for previous, F4 for next, ^A, D to disconnect. And ^A, & to kill a screen. Those are the only commands I've ever needed.
I should probably learn how to actually split a terminal, but I've never been in a situation that I couldn't just move the terminal emulator window.
