If you start emacs when using X11, the editor will launch in its own floating window. To force emacs to display inside a terminal window instead of its own window (which can be useful if the window is a login at a remote computer), use the -nw command-line option like this:
emacs -nw file.txt.
The emacs editor uses an extensive set of keystroke and named commands, but you can work with it using a basic command subset. Many of these basic commands require you to hold down the Ctrl key, or to first press a meta key (generally mapped to the Alt key). The basic commands are listed in Table 5.2.
