emacs 命令

常用示例

说明

emacs is an extensible, customizable, self-documenting text editor and computing environment. Far beyond a simple editor, it includes facilities for email, file management, terminal emulation, web browsing, and thousands of other functions through its extension system. Emacs is built around Emacs Lisp (Elisp), a full programming language that allows users to customize and extend virtually every aspect of the editor. User configurations are stored in ~/.emacs or ~/.emacs.d/init.el. The editor operates in different modes depending on the file type, providing syntax highlighting, indentation, and mode-specific commands. Major modes handle different file types, while minor modes add optional features. The built-in help system is accessed with C-h (Ctrl+h) or F1.
