The command C-x C-s saves the current Emacs buffer to disk as the currently named file. The buffer is not saved to a file on disk until you specifically request it with, for example, the C-x C-s command. ![]() ![]() You may then make changes to the buffer by typing and by using other Emacs commands. You are prompted for the name of the file to load. The command C-x C-f (press the Ctrl key, press and release x, press and release f, release Ctrl) loads a file on disk into an Emacs buffer (an Emacs working area) for editing. In this Emacs chapter, we employ the notation used in the Emacs documentation, which abbreviates ctrl + x as C-x. In most of this book, outside of this Emacs chapter, we use a notation like ctrl + x to denote depressing the Ctrl (Control) key, then pressing the x key while Ctrl is depressed, then releasing both keys. Once Emacs is running, there are a number of basic editing commands you can use. You can load a file for editing at the time you start Emacs by giving the file name after the emacs command. You may occasionally want to run Emacs directly in the terminal window. If you plan to have Emacs running for an extended time, it is helpful to run Emacs in the background or another virtual terminal so that the command line becomes available for another command. If you are using a typical graphics-based GNU/Linux distribution, this command opens a new window with Emacs running in that new window.ĭue to its versatility, many users find themselves resorting to Emacs constantly, and they open an Emacs session soon after turning their computer on and leave it open for the duration of their computing endeavor. You can invoke Emacs by typing its name at the command line. See EmacsManualFormats for discussion about the manual’s source markup language, output formats and usage.Emacs is a very powerful text editor. See EmacsManualLicense for some discussion about the manual’s license. The XEmacs manuals are also available online from here:ĮmacsLisp authors will want to look instead at the EmacsLispReference. You can provide context in parenthesis: it just needs to match somewhere in the URL or description of the particular entry you want to refer to. If we’re linking to macros or point, for example, we are shown two or more alternatives. You can also provide some context in parenthesis, after the link itself. Manual:show-paren-mode → show-paren-mode.If the entries contain punctuation or whitespace characters, you will need to put them in double square brackets: Command, Variable, and Concept index entries can be linked. You can link to the index entries in the manual using the Manual prefix. The GNU Emacs manual is also available online from any GNU ftp mirror or from here: ![]() Another option is to use ‘C-h R’ or ‘info-display-manual’ which will provide a list of manuals available, including the EmacsManual. Starting with Emacs 22, you can also read the manual with ‘C-h r’. Access it through Info, either with the info command in a shell window under GNU and Unix operating systems, or in Emacs, by typing ‘M-x info RET’ (that’s Meta- or ESC x, the word “info”, followed by the return key), or by typing ‘C-h i’ (that’s Control-h followed by i).
