How does one get back to "terminal content as a buffer" from the interactive version of the terminal?

from: https://neovim.io/doc/user/nvim_terminal_emulator.html

"In [terminal] mode all keys except <C-\><C-N> are sent to the underlying program. Use <C-\><C-N> to return to normal-mode."

This and more is explained in the doco.
