How do I use Emacs without X?
To start Emacs without a GUI window, use the -nw (no window) flag on the command line.
To access the menus without the mouse, use M-`. In non-emacspeak, that means press Esc, let go, then press the backtick. You will get a list of the menu functions in the minibuffer that you can scroll and select with the Enter key.
