If we didn't have GUIs, terminal multiplexers would be our desktop environments. E.g. they handle stuff like:
  • window switching
  • copy pasting across windows
  • screen locking
  • clock on the status bar (same one that holds tabs)
It is a thing of beauty.
Most important things to know:
  • kill window: Ctrl + A K
If session autosave was finally mainlined, this would be Nirvana.
