Emacs的基本使用
Emacs
Every buffer is edited in a mode. The most basic mode is Fundamental, which provides only the most basic Emacs editing features. There are modes for many different programming languages.
There are many "special" buffers that do not correspond to loaded files. The one above is called scratch. This buffer runs in Lisp Interaction mode, which means that you can interactively type and evaluate expressions in the Lisp programming language. But we won't do that.
