For example, you might define + a short word as an abbrev for a long phrase that you want to insert + frequently. *Note Abbrevs::. + +Aborting + Aborting means getting out of a recursive edit (q.v.). The + commands `C-]' and `M-x top-level' are used for this. *Note + Quitting::. + +Auto Fill mode + Auto Fill mode is a minor mode in which text that you insert is + automatically broken into lines of fixed width. *Note Filling::. + +Auto Saving + Auto saving is when Emacs automatically stores the contents of an + Emacs buffer in a specially-named file so that the information will + not be lost if the buffer is lost due to a system error or user + error. *Note Auto Save::. + +Backup File + A backup file records the contents that a file had before the + current editing session. Emacs makes backup files automatically + to help you track down or cancel changes you later regret making. + *Note Backup::. + +Balance Parentheses + Emacs can balance parentheses manually or automatically. Manual + balancing is done by the commands to move over balanced expressions + (*note Lists::.). Automatic balancing is done by blinking the + parenthesis that matches one just inserted (*note Matching Parens: + Matching.). + +Bind + To bind a key is to change its binding (q.v.). *Note Rebinding::. + +Binding + A key gets its meaning in Emacs by having a binding which is a + command (q.v.), a Lisp function that is run when the key is typed. + *Note Binding: Commands. Customization often involves rebinding a + character to a different command function. The bindings of all + keys are recorded in the keymaps (q.v.). *Note Keymaps::. + +Blank Lines + Blank lines are lines that contain only whitespace. Emacs has + several commands for operating on the blank lines in the buffer. + +Buffer + The buffer is the basic editing unit; one buffer corresponds to one + piece of text being edited. You can have several buffers, but at + any time you are editing only one, the `selected' buffer, though + several can be visible when you are using multiple windows. *Note + Buffers::. + +Buffer Selection History + Emacs keeps a buffer selection history which records how recently + each Emacs buffer has been selected. This is used for choosing a + buffer to select. *Note Buffers::. + +C- + `C' in the name of a character is an abbreviation for Control. + *Note C-: Characters. + +C-M- + `C-M-' in the name of a character is an abbreviation for + Control-Meta. *Note C-M-: Characters. + +Case Conversion + Case conversion means changing text from upper case to lower case + or vice versa. *Note Case::, for the commands for case conversion. + +Characters + Characters form the contents of an Emacs buffer; also, Emacs + commands are invoked by keys (q.v.), which are sequences of one or + more characters. *Note Characters::. + +Command + A command is a Lisp function specially defined to be able to serve + as a key binding in Emacs. When you type a key (q.v.), its binding + (q.v.) is looked up in the relevant keymaps (q.v.) to find the + command to run. *Note Commands::. + +Command Name + A command name is the name of a Lisp symbol which is a command + (*note Commands::.). You can invoke any command by its name using + `M-x' (*note M-x::.). + +Comments + A comment is text in a program which is intended only for humans + reading the program, and is marked specially so that it will be + ignored when the program is loaded or compiled. Emacs offers + special commands for creating, aligning and killing comments. + *Note Comments::. + +Compilation + Compilation is the process of creating an executable program from + source code. Emacs has commands for compiling files of Emacs Lisp + code (*note Lisp Libraries::.) and programs in C and other + languages (*note Compilation::.). + +Complete Key + A complete key is a character or sequence of characters which, + when typed by the user, fully specifies one action to be performed + by Emacs. For example, `X' and `Control-f' and `Control-x m' are + keys. Keys derive their meanings from being bound (q.v.) to + commands (q.v.). Thus, `X' is conventionally bound to a command to + insert `X' in the buffer; `C-x m' is conventionally bound to a + command to begin composing a mail message. *Note Keys::. + +Completion + Completion is what Emacs does when it automatically fills out an + abbreviation for a name into the entire name. Completion is done + for minibuffer (q.v.) arguments when the set of possible valid + inputs is known; for example, on command names, buffer names, and + file names. Completion occurs when TAB, SPC or RET is typed. + *Note Completion::. + +Continuation Line + When a line of text is longer than the width of the screen, it + takes up more than one screen line when displayed. We say that the + text line is continued, and all screen lines used for it after the + first are called continuation lines. *Note Continuation: Basic. + +Control-Character + ASCII characters with octal codes 0 through 037, and also code + 0177, do not have graphic images assigned to them. These are the + control characters. Any control character can be typed by holding + down the CTRL key and typing some other character; some have + special keys on the keyboard. RET, TAB, ESC, LFD and DEL are all + control characters. *Note Characters::. + +Copyleft + A copyleft is a notice giving the public legal permission to + redistribute a program or other work of art. Copylefts are used + by leftists to enrich the public just as copyrights are used by + rightists to gain power over the public. + +Current Buffer + The current buffer in Emacs is the Emacs buffer on which most + editing commands operate. You can select any Emacs buffer as the + current one. *Note Buffers::. + +Current Line + The line point is on (*note Point::.). + +Current Paragraph + The paragraph that point is in. If point is between paragraphs, + the current paragraph is the one that follows point. *Note + Paragraphs::. + +Current Defun + The defun (q.v.) that point is in. If point is between defuns, the + current defun is the one that follows point. *Note Defuns::. + +Cursor + The cursor is the rectangle on the screen which indicates the + position called point (q.v.) at which insertion and deletion takes + place. The cursor is on or under the character that follows point. + Often people speak of `the cursor' when, strictly speaking, they + mean `point'. *Note Cursor: Basic. + +Customization + Customization is making minor changes in the way Emacs works. It + is often done by setting variables (*note Variables::.) or by + rebinding keys (*note Keymaps::.). + +Default Argument + The default for an argument is the value that will be assumed if + you do not specify one. When the minibuffer is used to read an + argument, the default argument is used if you just type RET. *Note + Minibuffer::. + +Default Directory + When you specify a file name that does not start with `/' or `~', + it is interpreted relative to the current buffer's default + directory. *Note Default Directory: Minibuffer File. + +Defun + A defun is a list at the top level of parenthesis or bracket + structure in a program. It is so named because most such lists in + Lisp programs are calls to the Lisp function `defun'. *Note + Defuns::. + +DEL + DEL is a character that runs the command to delete one character of + text. *Note DEL: Basic. + +Deletion + Deletion means erasing text without saving it. Emacs deletes text + only when it is expected not to be worth saving (all whitespace, or + only one character). The alternative is killing (q.v.). *Note + Deletion: Killing. + +Deletion of Files + Deleting a file means erasing it from the file system. *Note Misc + File Ops::. + +Deletion of Messages + Deleting a message means flagging it to be eliminated from your + mail file. This can be undone by undeletion until the mail file + is expunged. *Note Rmail Deletion::. + +Deletion of Windows + Deleting a window means eliminating it from the screen. Other + windows expand to use up the space. The deleted window can never + come back, but no actual text is thereby lost. *Note Windows::. + +Directory + Files in the Unix file system are grouped into file directories. + *Note Directories: ListDir. + +Dired + Dired is the Emacs facility that displays the contents of a file + directory and allows you to "edit the directory", performing + operations on the files in the directory. *Note Dired::. + +Disabled Command + A disabled command is one that you may not run without special + confirmation. The usual reason for disabling a command is that it + is confusing for beginning users. *Note Disabling::. + +Dribble File + A file into which Emacs writes all the characters that the user + types on the keyboard. Dribble files are used to make a record for + debugging Emacs bugs. Emacs does not make a dribble file unless + you tell it to. *Note Bugs::. + +Echo Area + The echo area is the bottom line of the screen, used for echoing + the arguments to commands, for asking questions, and printing brief + messages (including error messages). *Note Echo Area::. + +Echoing + Echoing is acknowledging the receipt of commands by displaying them + (in the echo area). Emacs never echoes single-character keys; + longer keys echo only if you pause while typing them. + +Error + An error occurs when an Emacs command cannot execute in the current + circumstances. When an error occurs, execution of the command + stops (unless the command has been programmed to do otherwise) and + Emacs reports the error by printing an error message (q.v.). + Type-ahead is discarded. Then Emacs is ready to read another + editing command. + +Error Messages + Error messages are single lines of output printed by Emacs when the + user asks for something impossible to do (such as, killing text + forward when point is at the end of the buffer). They appear in + the echo area, accompanied by a beep. + +ESC + ESC is a character, used to end incremental searches and as a + prefix for typing Meta characters on keyboards lacking a META key. + Unlike the META key (which, like the SHIFT key, is held down + while another character is typed), the ESC key is pressed once and + applies to the next character typed. + +Fill Prefix + The fill prefix is a string that should be expected at the + beginning of each line when filling is done. It is not regarded + as part of the text to be filled. *Note Filling::. + +Filling + Filling text means moving text from line to line so that all the + lines are approximately the same length. *Note Filling::. + +Global + Global means `independent of the current environment; in effect + throughout Emacs'. It is the opposite of local (q.v.). Particular + examples of the use of `global' appear below. + +Global Abbrev + A global definition of an abbrev (q.v.) is effective in all major + modes that do not have local (q.v.) definitions for the same + abbrev. *Note Abbrevs::. + +Global Keymap + The global keymap (q.v.) contains key bindings that are in effect + except when overridden by local key bindings in a major mode's + local keymap (q.v.). *Note Keymaps::. + +Global Substitution + Global substitution means replacing each occurrence of one string + by another string through a large amount of text. *Note Replace::. + +Global Variable + The global value of a variable (q.v.) takes effect in all buffers + that do not have their own local (q.v.) values for the variable. + *Note Variables::. + +Graphic Character + Graphic characters are those assigned pictorial images rather than + just names. All the non-Meta (q.v.) characters except for the + Control (q.v.) characters are graphic characters. These include + letters, digits, punctuation, and spaces; they do not include RET + or ESC. In Emacs, typing a graphic character inserts that + character (in ordinary editing modes). *Note Basic Editing: Basic. + +Grinding + Grinding means adjusting the indentation in a program to fit the + nesting structure. *Note Grinding: Indentation. + +Hardcopy + Hardcopy means printed output. Emacs has commands for making + printed listings of text in Emacs buffers. *Note Hardcopy::. + +HELP + You can type HELP at any time to ask what options you have, or to + ask what any command does. HELP is really `Control-h'. *Note + Help::. + +Inbox + An inbox is a file in which mail is delivered by the operating + system. Rmail transfers mail from inboxes to mail files (q.v.) in + which the mail is then stored permanently or until explicitly + deleted. *Note Rmail Inbox::. + +Indentation + Indentation means blank space at the beginning of a line. Most + programming languages have conventions for using indentation to + illuminate the structure of the program, and Emacs has special + features to help you set up the correct indentation. *Note + Indentation::. + +Insertion + Insertion means copying text into the buffer, either from the + keyboard or from some other place in Emacs. + +Justification + Justification means adding extra spaces to lines of text to make + them come exactly to a specified width. *Note Justification: + Filling. + +Keyboard Macros + Keyboard macros are a way of defining new Emacs commands from + sequences of existing ones, with no need to write a Lisp program. + *Note Keyboard Macros::. + +Key + A key is a sequence of characters that, when input to Emacs, + specify or begin to specify a single action for Emacs to perform. + That is, the sequence is not more than a single unit. If the key + is enough to specify one action, it is a complete key (q.v.); if + it is less than enough, it is a prefix key (q.v.). *Note Keys::. + +Keymap + The keymap is the data structure that records the bindings (q.v.) + of keys to the commands that they run. For example, the keymap + binds the character `C-n' to the command function `next-line'. + *Note Keymaps::. + +Kill Ring + The kill ring is where all text you have killed recently is saved. + You can reinsert any of the killed text still in the ring; this is + called yanking (q.v.). *Note Yanking::. + +Killing + Killing means erasing text and saving it on the kill ring so it + can be yanked (q.v.) later. Some other systems call this + "cutting". Most Emacs commands to erase text do killing, as + opposed to deletion (q.v.). *Note Killing::. + +Killing Jobs + Killing a job (such as, an invocation of Emacs) means making it + cease to exist. Any data within it, if not saved in a file, is + lost. *Note Exiting::. + +List + A list is, approximately, a text string beginning with an open + parenthesis and ending with the matching close parenthesis. In C + mode and other non-Lisp modes, groupings surrounded by other kinds + of matched delimiters appropriate to the language, such as braces, + are also considered lists. Emacs has special commands for many + operations on lists. *Note Lists::. + +Local + Local means `in effect only in a particular context'; the relevant + kind of context is a particular function execution, a particular + buffer, or a particular major mode. It is the opposite of `global' + (q.v.). Specific uses of `local' in Emacs terminology appear + below. + +Local Abbrev + A local abbrev definition is effective only if a particular major + mode is selected. In that major mode, it overrides any global + definition for the same abbrev. *Note Abbrevs::. + +Local Keymap + A local keymap is used in a particular major mode; the key bindings + (q.v.) in the current local keymap override global bindings of the + same keys. *Note Keymaps::. + +Local Variable + A local value of a variable (q.v.) applies to only one buffer. + *Note Locals::. + +M- + `M-' in the name of a character is an abbreviation for META, one + of the modifier keys that can accompany any character. *Note + Characters::. + +M-C- + `M-C-' in the name of a character is an abbreviation for + Control-Meta; it means the same thing as `C-M-'. If your terminal + lacks a real META key, you type a Control-Meta character by typing + ESC and then typing the corresponding Control character. *Note + C-M-: Characters. + +M-x + `M-x' is the key which is used to call an Emacs command by name. + This is how commands that are not bound to keys are called. *Note + M-x::. + +Mail + Mail means messages sent from one user to another through the + computer system, to be read at the recipient's convenience. Emacs + has commands for composing and sending mail, and for reading and + editing the mail you have received. *Note Sending Mail::. *Note + Rmail::, for how to read mail. + +Mail File + A mail file is a file which is edited using Rmail and in which + Rmail stores mail. *Note Rmail::. + +Major Mode + The major modes are a mutually exclusive set of options each of + which configures Emacs for editing a certain sort of text. + Ideally, each programming language has its own major mode. *Note + Major Modes::. + +Mark + The mark points to a position in the text. It specifies one end of + the region (q.v.), point being the other end. Many commands + operate on all the text from point to the mark. *Note Mark::. + +Mark Ring + The mark ring is used to hold several recent previous locations of + the mark, just in case you want to move back to them. *Note Mark + Ring::. + +Message + See `mail'. + +Meta + Meta is the name of a modifier bit which a command character may + have. It is present in a character if the character is typed with + the META key held down. Such characters are given names that start + with `Meta-'. For example, `Meta-<' is typed by holding down META + and at the same time typing `<' (which itself is done, on most + terminals, by holding down SHIFT and typing `,'). *Note Meta: + Characters. + +Meta Character + A Meta character is one whose character code includes the Meta bit. + +Minibuffer + The minibuffer is the window that appears when necessary inside the + echo area (q.v.), used for reading arguments to commands. *Note + Minibuffer::. + +Minor Mode + A minor mode is an optional feature of Emacs which can be switched + on or off independently of all other features. Each minor mode + has a command to turn it on or off. *Note Minor Modes::. + +Mode Line + The mode line is the line at the bottom of each text window (q.v.), + which gives status information on the buffer displayed in that + window. *Note Mode Line::. + +Modified Buffer + A buffer (q.v.) is modified if its text has been changed since the + last time the buffer was saved (or since when it was created, if it + has never been saved). *Note Saving::. + +Moving Text + Moving text means erasing it from one place and inserting it in + another. This is done by killing (q.v.) and then yanking (q.v.). + *Note Killing::. + +Named Mark + A named mark is a register (q.v.) in its role of recording a + location in text so that you can move point to that location. + *Note Registers::. + +Narrowing + Narrowing means creating a restriction (q.v.) that limits editing + in the current buffer to only a part of the text in the buffer. + Text outside that part is inaccessible to the user until the + boundaries are widened again, but it is still there, and saving + the file saves it all. *Note Narrowing::. + +Newline + LFD characters in the buffer terminate lines of text and are + called newlines. *Note Newline: Characters. + +Numeric Argument + A numeric argument is a number, specified before a command, to + change the effect of the command. Often the numeric argument + serves as a repeat count. *Note Arguments::. + +Option + An option is a variable (q.v.) that exists so that you can + customize Emacs by giving it a new value. *Note Variables::. + +Overwrite Mode + Overwrite mode is a minor mode. When it is enabled, ordinary text + characters replace the existing text after point rather than + pushing it to the right. *Note Minor Modes::. + +Page + A page is a unit of text, delimited by formfeed characters (ASCII + Control-L, code 014) coming at the beginning of a line. Some Emacs + commands are provided for moving over and operating on pages. + *Note Pages::. + +Paragraphs + Paragraphs are the medium-size unit of English text. There are + special Emacs commands for moving over and operating on paragraphs. + *Note Paragraphs::. + +Parsing + We say that Emacs parses words or expressions in the text being + edited. Really, all it knows how to do is find the other end of a + word or expression. *Note Syntax::. + +Point + Point is the place in the buffer at which insertion and deletion + occur. Point is considered to be between two characters, not at + one character. The terminal's cursor (q.v.) indicates the + location of point. *Note Point: Basic. + +Prefix Key + A prefix key is a key (q.v.) whose sole function is to introduce a + set of multi-character keys. `Control-x' is an example of prefix + key; thus, any two-character sequence starting with `C-x' is also + a legitimate key. *Note Keys::. + +Primary Mail File + Your primary mail file is the file named `RMAIL' in your home + directory, where all mail that you receive is stored by Rmail + unless you make arrangements to do otherwise. *Note Rmail::. + +Prompt + A prompt is text printed to ask the user for input. Printing a + prompt is called prompting. Emacs prompts always appear in the + echo area (q.v.). One kind of prompting happens when the + minibuffer is used to read an argument (*note Minibuffer::.); the + echoing which happens when you pause in the middle of typing a + multicharacter key is also a kind of prompting (*note Echo + Area::.). + +Quitting + Quitting means cancelling a partially typed command or a running + command, using `C-g'. *Note Quitting::. + +Quoting + Quoting means depriving a character of its usual special + significance. In Emacs this is usually done with `Control-q'. + What constitutes special significance depends on the context and + on convention. For example, an "ordinary" character as an Emacs + command inserts itself; so in this context, a special character is + any character that does not normally insert itself (such as DEL, + for example), and quoting it makes it insert itself as if it were + not special. Not all contexts allow quoting. *Note Quoting: + Basic. + +Read-only Buffer + A read-only buffer is one whose text you are not allowed to change. + Normally Emacs makes buffers read-only when they contain text which + has a special significance to Emacs; for example, Dired buffers. + Visiting a file that is write protected also makes a read-only + buffer. *Note Buffers::. + +Recursive Editing Level + A recursive editing level is a state in which part of the + execution of a command involves asking the user to edit some text. + This text may or may not be the same as the text to which the + command was applied. The mode line indicates recursive editing + levels with square brackets (`[' and `]'). *Note Recursive Edit::. + +Redisplay + Redisplay is the process of correcting the image on the screen to + correspond to changes that have been made in the text being edited. + *Note Redisplay: Screen. + +Regexp + See `regular expression'. + +Region + The region is the text between point (q.v.) and the mark (q.v.). + Many commands operate on the text of the region. *Note Region: + Mark. + +Registers + Registers are named slots in which text or buffer positions or + rectangles can be saved for later use. *Note Registers::. + +Regular Expression + A regular expression is a pattern that can match various text + strings; for example, `l[0-9]+' matches `l' followed by one or more + digits. *Note Regexps::. + +Replacement + See `global substitution'. + +Restriction + A buffer's restriction is the amount of text, at the beginning or + the end of the buffer, that is temporarily invisible and + inaccessible. Giving a buffer a nonzero amount of restriction is + called narrowing (q.v.). *Note Narrowing::. + +RET + RET is a character that in Emacs runs the command to insert a + newline into the text. It is also used to terminate most arguments + read in the minibuffer (q.v.). *Note Return: Characters. + +Saving + Saving a buffer means copying its text into the file that was + visited (q.v.) in that buffer. This is the way text in files + actually gets changed by your Emacs editing. *Note Saving::. + +Scrolling + Scrolling means shifting the text in the Emacs window so as to see + a different part of the buffer. *Note Scrolling: Display. + +Searching + Searching means moving point to the next occurrence of a specified + string. *Note Search::. + +Selecting + Selecting a buffer means making it the current (q.v.) buffer. + *Note Selecting: Buffers. + +Self-documentation + Self-documentation is the feature of Emacs which can tell you what + any command does, or give you a list of all commands related to a + topic you specify. You ask for self-documentation with the help + character, `C-h'. *Note Help::. + +Sentences + Emacs has commands for moving by or killing by sentences. *Note + Sentences::. + +Sexp + A sexp (short for `s-expression') is the basic syntactic unit of + Lisp in its textual form: either a list, or Lisp atom. Many Emacs + commands operate on sexps. The term `sexp' is generalized to + languages other than Lisp, to mean a syntactically recognizable + expression. *Note Sexps: Lists. + +Simultaneous Editing + Simultaneous editing means two users modifying the same file at + once. Simultaneous editing if not detected can cause one user to + lose his work. Emacs detects all cases of simultaneous editing + and warns the user to investigate them. *Note Simultaneous + Editing: Interlocking. + +String + A string is a kind of Lisp data object which contains a sequence of + characters. Many Emacs variables are intended to have strings as + values. The Lisp syntax for a string consists of the characters in + the string with a `"' before and another `"' after. A `"' that is + part of the string must be written as `\"' and a `\' that is part + of the string must be written as `\\'. All other characters, + including newline, can be included just by writing them inside the + string; however, escape sequences as in C, such as `\n' for + newline or `\241' using an octal character code, are allowed as + well. + +String Substitution + See `global substitution'. + +Syntax Table + The syntax table tells Emacs which characters are part of a word, + which characters balance each other like parentheses, etc. *Note + Syntax::. + +Tag Table + A tag table is a file that serves as an index to the function + definitions in one or more other files. *Note Tags::. + +Termscript File + A termscript file contains a record of all characters sent by + Emacs to the terminal. It is used for tracking down bugs in Emacs + redisplay. Emacs does not make a termscript file unless you tell + it to. *Note Bugs::. + +Text + Two meanings (*note Text::.): + + * Data consisting of a sequence of characters, as opposed to + binary numbers, images, graphics commands, executable + programs, and the like. The contents of an Emacs buffer are + always text in this sense. + + * Data consisting of written human language, as opposed to + programs, or following the stylistic conventions of human + language. + +Top Level + Top level is the normal state of Emacs, in which you are editing + the text of the file you have visited. You are at top level + whenever you are not in a recursive editing level (q.v.) or the + minibuffer (q.v.), and not in the middle of a command. You can + get back to top level by aborting (q.v.) and quitting (q.v.). + *Note Quitting::. + +Transposition + Transposing two units of text means putting each one into the place + formerly occupied by the other. There are Emacs commands to + transpose two adjacent characters, words, sexps (q.v.) or lines + (*note Transpose::.). + +Truncation + Truncating text lines in the display means leaving out any text on + a line that does not fit within the right margin of the window + displaying it. See also `continuation line'. *Note Truncation: + Basic. + +Undoing + Undoing means making your previous editing go in reverse, bringing + back the text that existed earlier in the editing session. *Note + Undo::. + +Variable + A variable is an object in Lisp that can store an arbitrary value. + Emacs uses some variables for internal purposes, and has others + (known as `options' (q.v.)) just so that you can set their values + to control the behavior of Emacs. The variables used in Emacs + that you are likely to be interested in are listed in the + Variables Index in this manual. *Note Variables::, for + information on variables. + +Visiting + Visiting a file means loading its contents into a buffer (q.v.) + where they can be edited. *Note Visiting::. + +Whitespace + Whitespace is any run of consecutive formatting characters (space, + tab, newline, and backspace). + +Widening + Widening is removing any restriction (q.v.) on the current buffer; + it is the opposite of narrowing (q.v.). *Note Narrowing::. + +Window + Emacs divides the screen into one or more windows, each of which + can display the contents of one buffer (q.v.) at any time. *Note + Screen::, for basic information on how Emacs uses the screen. + *Note Windows::, for commands to control the use of windows. + +Word Abbrev + Synonymous with `abbrev'. + +Word Search + Word search is searching for a sequence of words, considering the + punctuation between them as insignificant. *Note Word Search::. + +Yanking + Yanking means reinserting text previously killed. It can be used + to undo a mistaken kill, or for copying or moving text. Some other + systems call this "pasting". *Note Yanking::. + +
