 ===== Emacs Cheat Sheet ===== ===== Emacs Cheat Sheet =====
  
 +While Emacs can be simple to use, its scope can easily be
 +overwhelming. ​ Below are some useful Emacs commands. ​ Some
 +aspects have been simplified, most notably regarding text
 +selection. ​ These concepts, and more, are described the
 +**//​Emacs//​** manual, and various on-line
 +tutorials. ​ Decent summaries can also be gleaned from web
 +searches.
  
  
-While [[slackbook:​vi|vi]] (with its clonesis without a doubt the most ubiquitous editor on Unix-like systems, emacs(1comes in a good second. Instead of using different "​modes",​ like vi does, it uses <key>Ctrl</​key> ​and <key>Alt</​key>​ key combinations to enter commands, in much the same way that you can use <key>Ctrl</​key> ​and <key>Alt</​key>​ key combinations in a word processor and indeed in many other applications ​to execute certain functions. (Though it should be noted that the commands rarely correspond; so while many modern applications use <key>Ctrl+C/X/V</​key> ​for copying, cutting and pasting, emacs uses different keys and actually a somewhat different mechanism for this.) +**Emacs Cheat Sheet** 
- +^Command^Result| 
-Also unlike vi, which is an (excellent) editor and nothing more, emacs is a program with near endless capabilitiesemacs is (for the most part) written ​in Lisp, which is a very powerful programming language that has the peculiar property that every program written in it is automatically a Lisp compiler of its ownThis means that the user can extend emacs, and in fact write completely new programs "in emacs"​. +|<​key>​C-f</​key>​ |Move the cursor one character to the right (forward)
- +|<​key>​C-b</​key>​ |Move ​the cursor one character to the left (backward)| 
-As a result, emacs is not just an editor anymore. There are many add-on packages for emacs available ​(many come with the program's source) that provide all sorts of functionality. Many of these are related ​to text editing, which is after all emacs' ​basic task, but it doesn't stop thereThere are for example several spreadsheet programs for emacsthere are databasesgames, mail and news clients (the top one being Gnus)etc+|<​key>​C-n</​key>​ |Move the cursor one line down (next)

-There are two main versions ​of emacs: GNU Emacs (which is the version that comes with Slackware) ​and XEmacsThe latter is not a version for Emacs running under X. In factboth emacs and XEmacs run on the console as well as under XXEmacs was once started ​as a project ​to tidy up the emacs codeCurrently, both versions are being actively developed, and there is in fact much interaction between the two development teamsFor the present chapterit is immaterial whether ​you use emacs or XEmacs, ​the differences between them are not relevant ​to the normal user. +|<key>C-h</​key> ​<key>'​f'​</key> ​FUNCTION-NAME <​key>​Enter</​key>​ |Show documentation for function FUNCTION-NAME|
