! 3: You are looking at the Emacs tutorial.
! 4:
! 5: Emacs commands generally involve the CONTROL key or the META (ESC)
! 6: key. Rather than write out META or CONTROL each time we want you to
! 7: prefix a character, we'll use the following abbreviations:
! 8:
! 9: C-<chr> means hold the CONTROL key while typing the character <chr>
! 10: Thus, C-f would be: hold the CONTROL key and type f.
! 11: M-<chr> means type <ESC>, release it, then type the character <chr>.
! 12:
! 13: The characters ">>" at the left margin indicate directions for you to
! 14: try using a command. For instance:
! 15:
! 16: >> Now type C-v (View next screen) to move to the next screen.
! 17: (go ahead, do it by depressing the control key and v together).
! 18: From now on, you'll be expected to do this whenever you finish
! 19: reading the screen.
! 20:
! 21: Note that there is an overlap when going from screen to screen; this
! 22: provides some continuity when moving through the file.
! 23:
! 24: The first thing that you need to know is how to move around from
! 25: place to place in the file. You already know how to move forward a
! 26: screen, with C-v. To move backwards a screen, type M-v (type <ESC>v).
! 27:
! 28: >> Try typing M-v and then C-v to move back and forth a few times.
! 29:
! 30:
! 31: SUMMARY
! 32: -------
! 33:
! 34: The following commands are useful for viewing screenfuls:
! 35:
! 36: C-v Move forward one screenful
! 37: M-v Move backward one screenful
! 38: C-l Clear screen and redisplay everything
! 39: putting the text near the cursor at the center.
! 40: (That's control-L, not control-1.
! 41: There is no such character as control-1.)
! 42:
! 43: >> Find the cursor and remember what text is near it.
! 44: Then type a C-l.
! 45: Find the cursor again and see what text is near it now.
! 46:
! 47:
! 48: BASIC CURSOR CONTROL
! 49: --------------------
! 50:
! 51: Getting from screenful to screenful is useful, but how do you
! 52: reposition yourself within a given screen to a specific place? There
! 53: are several ways you can do this. One way (not the best, but the most
! 54: basic) is to use the commands previous, backward, forward and next.
! 55: As you can imagine these commands (which are given to Emacs as C-p,
! 56: C-b, C-f, and C-n respectively) move the cursor from where it
! 57: currently is to a new place in the given direction. It is also
! 58: possible to move the cursor with the arrow keys, but this requires you
! 59: move your hand from the keyboard, it is also not supported on other
! 60: machines that do support Emacs. Emacs runs on everything from a CP/M
! 61: machine to large mainframes. Here then, in a more graphical form are
! 62: the commands:
! 63:
! 64: Previous line, C-p
! 65: :
! 66: :
! 67: Backward, C-b .... Current cursor position .... Forward, C-f
! 68: :
! 69: :
! 70: Next line, C-n
! 71:
! 72: >> Move the cursor to the line in the middle of that diagram
! 73: and type C-l to see the whole diagram centered in the screen.
! 74:
! 75: You'll probably find it easy to think of these by letter. P for
! 76: previous, N for next, B for backward and F for forward. These are
! 77: the basic cursor positioning commands and you'll be using them ALL
! 78: the time so it would be of great benefit if you learn them now.
! 79:
! 80: >> Do a few C-n's to bring the cursor down to this line.
! 81:
! 82: >> Move into the line with C-f's and then up with C-p's.
! 83: See what C-p does when the cursor is in the middle of the line.
! 84:
! 85: >> Try to C-b at the beginning of a line. Do a few more C-b's.
! 86: Then do C-f's back to the end of the line and beyond.
! 87:
! 88: When you go off the top or bottom of the screen, the text beyond
! 89: the edge is shifted onto the screen so that your instructions can
! 90: be carried out while keeping the cursor on the screen.
! 91:
! 92: >> Try to move the cursor off the bottom of the screen with C-n and
! 93: see what happens.
! 94:
! 95: If moving by characters is too slow, you can move by words. M-f
! 96: (ESC-f) moves forward a word and M-b moves back a word.
! 97:
! 98: >> Type a few M-f's and M-b's. Intersperse them with C-f's and C-b's.
! 99:
! 100: Notice the parallel between C-f and C-b on the one hand, and M-f and
! 101: M-b on the other hand. Very often Meta characters are used for
! 102: operations related to English text whereas Control characters operate
! 103: on the basic textual units that are independent of what you are
! 104: editing (characters, lines, etc). C-a and C-e move to the beginning or
! 105: end of a line.
! 106:
! 107: >> Try a couple of C-a's, and then a couple of C-e's.
! 108: See how repeated C-a's do nothing.
! 109:
! 110: Two other simple cursor motion commands are M-< (Meta Less-than),
! 111: which moves to the beginning of the file, and M-> (Meta Greater-than),
! 112: which moves to the end of the file. You probably don't need to try
! 113: them, since finding this spot again will be boring. On most terminals
! 114: the "<" is above the comma and you must use the shift key to type it.
! 115: On these terminals you must use the shift key to type M-< also;
! 116: without the shift key, you would be typing M-comma.
! 117:
! 118: The location of the cursor in the text is also called "point". To
! 119: paraphrase, the cursor shows on the screen where point is located in
! 120: the text.
! 121:
! 122: Here is a summary of simple moving operations including the word and
! 123: sentence moving commands:
! 124:
! 125: C-f Move forward a character
! 126: C-b Move backward a character
! 127:
! 128: M-f Move forward a word
! 129: M-b Move backward a word
! 130:
! 131: c-n Move to next line
! 132: C-p Move to previous line
! 133:
! 134: C-a Move to beginning of line
! 135: C-e Move to end of line
! 136:
! 137: M-< Go to beginning of file
! 138: M-> Go to end of file
! 139:
! 140: >> Try all of these commands now a few times for practice.
! 141: Since the last two will take you away from this screen,
! 142: you can come back here with M-v's and C-v's. These are
! 143: the most often used commands.
! 144:
! 145: Like all other commands in Emacs, these commands can be given
! 146: arguments which cause them to be executed repeatedly. The way you
! 147: give a command a repeat count is by typing C-u and then the digits
! 148: before you type the command.
! 149:
! 150: For instance, C-u 8 C-f moves forward eight characters.
! 151:
! 152: >> Try giving a suitable argument to C-n or C-p to come as close
! 153: as you can to this line in one jump.
! 154:
! 155: The only apparent exception to this is the screen moving commands,
! 156: C-v and M-v. When given an argument, they scroll the screen up or
! 157: down by that many lines, rather than screenfuls. This proves to be
! 158: much more useful.
! 159:
! 160: >> Try typing C-u 8 C-v now.
! 161:
! 162: Did it scroll the screen up by 8 lines? If you would like to
! 163: scroll it down you can give an argument to M-v.
! 164:
! 165:
! 166: WHEN EMACS IS HUNG
! 167: -----------------
! 168:
! 169: If Emacs gets into an infinite (or simply very long) computation which
! 170: you don't want to finish, you can stop it safely by typing C-g.
! 171: You can also use C-g to discard a numeric argument or the beginning of
! 172: a command that you don't want to finish.
! 173:
! 174: >> Type C-u 100 to make a numeric arg of 100, then type C-g.
! 175: Now type C-f. How many characters does it move?
! 176: If you have typed an <ESC> by mistake, you can get rid of it
! 177: with a C-g.
! 178:
! 179: WINDOWS
! 180: -------
! 181:
! 182: Emacs can have several windows, each displaying its own text.
! 183: At this stage it is better not to go into the techniques of
! 184: using multiple windows. But you do need to know how to get
! 185: rid of extra windows that may appear to display help or
! 186: output from certain commands. It is simple:
! 187:
! 188: C-x 1 One window (i.e., kill all other windows).
! 189:
! 190: That is Control-x followed by the digit 1.
! 191: C-x 1 makes the window which the cursor is in become
! 192: the full screen, by getting rid of any other windows.
! 193:
! 194: >> Move the cursor to this line and type C-l (Control-L).
! 195: >> Type M-x. The cursor will move to the bottom of the screen.
! 196: >> Type the words "describe-bindings" and hit return.
! 197: See how this window shrinks, while a new one appears
! 198: to display which functions are connected to which keys.
! 199:
! 200: >> Type C-x 1 and see the documentation listing window disappear.
! 201:
! 202:
! 203: INSERTING AND DELETING
! 204: ----------------------
! 205:
! 206: If you want to insert text, just type it. Characters which you can
! 207: see, such as A, 7, *, etc. are taken by Emacs as text and inserted
! 208: immediately. Type <Return> (the carriage-return key) to insert a
! 209: Newline character.
! 210:
! 211: You can delete the last character you typed by typing <DEL>. More
! 212: generally, <DEL> deletes the character immediately before the current
! 213: cursor position.
! 214:
! 215: >> Do this now, type a few characters and then delete them
! 216: by typing <DEL> a few times. Don't worry about this file
! 217: being changed; you won't affect the master tutorial. This is just
! 218: a copy of it.
! 219:
! 220: >> Now start typing text until you reach the right margin, and keep
! 221: typing. When a line of text gets too big for one line on the
! 222: screen, the line of text is "continued" off the edge of the screen.
! 223: The dollar sign at the right margin indicates a line which has
! 224: been continued.
! 225: >> Use <DEL>s to delete the text until the line fits on one screen
! 226: line again. The continuation mark goes away.
! 227:
! 228: >> Move the cursor to the beginning of a line and type <DEL>. This
! 229: deletes the newline before the line and merges the line onto
! 230: the previous line. The resulting line may be too long to fit, in
! 231: which case it has a continuation mark.
! 232: >> Type <Return> to reinsert the Newline you deleted.
! 233:
! 234: Remember that most Emacs commands can be given a repeat count;
! 235: this includes characters which insert themselves.
! 236:
! 237: >> Try that now -- type C-u 8 * and see what happens.
! 238:
! 239: You've now learned the most basic way of typing something in
! 240: Emacs and correcting errors. You can delete by words or lines
! 241: as well. Here is a summary of the delete operations:
! 242:
! 243: <DEL> delete the character just before the cursor
! 244: C-d delete the next character after the cursor
! 245:
! 246: M-<DEL> kill the word immediately before the cursor
! 247: M-d kill the next word after the cursor
! 248:
! 249: C-k kill from the cursor position to end of line
! 250:
! 251: Notice that <DEL> and C-d vs M-<DEL> and M-d extend the parallel
! 252: started by C-f and M-f (well, <DEL> isn't really a control
! 253: character, but let's not worry about that).
! 254:
! 255: Now suppose you kill something, and then you decide that you want to
! 256: get it back? Well, whenever you kill something bigger than a
! 257: character, Emacs saves it for you. To yank it back, use C-y. You
! 258: can kill text in one place, move elsewhere, and then do C-y; this is
! 259: a good way to move text around. Note that the difference
! 260: between "Killing" and "Deleting" something is that "Killed" things
! 261: can be yanked back, and "Deleted" things cannot. Generally, the
! 262: commands that can destroy a lot of text save it, while the ones that
! 263: attack only one character, or nothing but blank lines and spaces, do
! 264: not save.
! 265:
! 266: For instance, type C-n a couple times to postion the cursor
! 267: at some line on this screen.
! 268:
! 269: >> Do this now, move the cursor and kill that line with C-k.
! 270:
! 271: Note that a single C-k kills the contents of the line, and a second
! 272: C-k kills the line itself, and make all the other lines move up. If
! 273: you give C-k a repeat count, it kills that many lines AND their
! 274: contents.
! 275:
! 276: The text that has just disappeared is saved so that you can
! 277: retrieve it. To retrieve the last killed text and put it where
! 278: the cursor currently is, type C-y.
! 279:
! 280: >> Try it; type C-y to yank the text back.
! 281:
! 282: Think of C-y as if you were yanking something back that someone
! 283: took away from you. Notice that if you do several C-k's in a row
! 284: the text that is killed is all saved together so that one C-y will
! 285: yank all of the lines.
! 286:
! 287: >> Do this now, type C-k several times.
! 288:
! 289: Now to retrieve that killed text:
! 290:
! 291: >> Type C-y. Then move the cursor down a few lines and type C-y
! 292: again. You now see how to copy some text.
! 293:
! 294:
! 295: FILES
! 296: -----
! 297:
! 298: In order to make the text you edit permanent, you must put it in a
! 299: file. Otherwise, it will go away when your invocation of Emacs goes
! 300: away. You put your editing in a file by "finding" the file. What
! 301: finding means is that you see the contents of the file in your Emacs;
! 302: and, loosely speaking, what you are editing is the file itself.
! 303: However, the changes still don't become permanent until you "save" the
! 304: file. This is so you can have control to avoid leaving a half-changed
! 305: file around when you don't want to.
! 306:
! 307: If you look near the bottom of the screen you will see a line that
! 308: begins and ends with dashes, and contains the string:
! 309: "Mg: TUTORIAL"
! 310: Your copy of the Emacs tutorial is called "TUTORIAL". Whatever
! 311: file you find, that file's name will appear in that precise
! 312: spot.
! 313:
! 314: The commands for finding and saving files are unlike the other
! 315: commands you have learned in that they consist of two characters.
! 316: They both start with the character Control-x. There is a whole series
! 317: of commands that start with Control-x; many of them have to do with
! 318: files, buffers, and related things, and all of them consist of
! 319: Control-x followed by some other character.
! 320:
! 321: Another thing about the command for finding a file is that you have
! 322: to say what file name you want. We say the command "reads an argument
! 323: from the terminal" (in this case, the argument is the name of the
! 324: file). After you type the command
! 325:
! 326: C-x C-f Find a file
! 327:
! 328: Emacs asks you to type the file name. It echoes on the bottom line of
! 329: the screen. When you type <Return> to end the file name it disappears.
! 330:
! 331: >> Type C-x C-f, then type C-g. This cancels the C-x C-f command
! 332: that was using the minibuffer. So you do not find any file.
! 333:
! 334: In a little while the file contents appear on the screen. You can
! 335: edit the contents. When you wish to make the changes permanent,
! 336: issue the command
! 337:
! 338: C-x C-s Save the file
! 339:
! 340: The contents of Emacs are written into the file.
! 341:
! 342: When saving is finished, Emacs prints the name of the file written.
! 343: You should save fairly often, so that you will not lose very much
! 344: work if the system should crash.
! 345:
! 346: >> Type C-x C-s, saving your copy of the tutorial.
! 347: This should print "Wrote TUTORIAL" at the bottom of the screen.
! 348:
! 349: To make a new file, just find it "as if" it already existed. Then
! 350: start typing in the text. When you ask to "save" the file, Emacs
! 351: will really create the file with the text that you have inserted.
! 352: >From then on, you can consider yourself to be editing an already
! 353: existing file.
! 354:
! 355:
! 356: BUFFERS
! 357: -------
! 358:
! 359: If you find a second file with C-x C-f, the first file remains inside
! 360: Emacs. This way you can get quite a number of files inside Emacs.
! 361:
! 362: The object inside Emacs which holds the text read from one file
! 363: is called a "buffer." Finding a file makes a new buffer inside Emacs.
! 364: To see a list of the buffers that exist in Emacs, type
! 365:
! 366: C-x C-b List buffers
! 367:
! 368: >> Try C-x C-b now.
! 369:
! 370: See how each buffer has a name, and it may also have a file name
! 371: for the file whose contents it holds. Some buffers do not correspond
! 372: to files. For example, the buffer named "*Buffer List*" does
! 373: not have any file. It is the buffer which contains the buffer
! 374: list that was made by C-x C-b. ANY text you see in an Emacs window
! 375: has to be in some buffer.
! 376:
! 377: >> Type C-x 1 to get rid of the buffer list.
! 378:
! 379: If you make changes to the text of one file, then find another file,
! 380: this does not save the first file. Its changes remain inside Emacs,
! 381: in that file's buffer. The creation or editing of the second file's
! 382: buffer has no effect on the first file's buffer. This is very useful,
! 383: but it also means that you need a convenient way to save the first
! 384: file's buffer. It would be a nuisance to have to switch back to
! 385: it with C-x C-f in order to save it with C-x C-s. So we have
! 386:
! 387: C-x s Save some buffers
! 388:
! 389: C-x s goes through the list of all the buffers you have
! 390: and finds the ones that contain files you have changed.
! 391: For each such buffer, C-x s asks you whether to save it.
! 392:
! 393:
! 394: EXTENDING THE COMMAND SET
! 395: -------------------------
! 396:
! 397: There are many, many more Emacs commands than could possibly be put
! 398: on all the control and meta characters. Emacs gets around this with
! 399: the X (eXtend) command. This comes in two flavors:
! 400:
! 401: C-x Character eXtend. Followed by one character.
! 402: M-x Named command eXtend. Followed by a long name.
! 403:
! 404: These are commands that are generally useful but used less than the
! 405: commands you have already learned about. You have already seen two
! 406: of them: the file commands C-x C-f to Find and C-x C-s to Save.
! 407: Another example is the command to tell Emacs that you'd like to stop
! 408: editing and get rid of Emacs. The command to do this is C-x C-c.
! 409: (Don't worry; it offers to save each changed file before it kills the
! 410: Emacs.)
! 411:
! 412: C-z is the usual way to exit Emacs, because it is always better not to
! 413: kill the Emacs if you are going to do any more editing. On systems
! 414: which allow it, C-z exits from Emacs to a CLI but does not destroy the
! 415: Emacs; you can resume editing by ending that CLI or depth arranging.
! 416:
! 417: You would use C-x C-c if you were running out of memory. You would
! 418: also use it to exit an Emacs invoked under mail handling programs and
! 419: other random utilities, since they may not believe you have really
! 420: finished using the Emacs if it continues to exist.
! 421:
! 422: There are many C-x commands. The ones you know are:
! 423:
! 424: C-x C-f Find file.
! 425: C-x C-s Save file.
! 426: C-x C-b List buffers.
! 427: C-x C-c Quit Emacs.
! 428:
! 429: Named eXtended commands are commands which are used even less
! 430: frequently, or commands which are used only in certain modes. These
! 431: commands are usually called "functions". An example is the function
! 432: replace-string, which globally replaces one string with another. When
! 433: you type M-x, Emacs prompts you at the bottom of the screen with
! 434: M-x and you should type the name of the function you wish to call; in
! 435: this case, "query-replace". Just type "que<TAB>" and Emacs will
! 436: complete the name. End the command name with <Return>.
! 437: Then type the two "arguments"--the string to be replaced, and the string
! 438: to replace it with--each one ended with a Return.
! 439:
! 440: >> Move the cursor to the blank line two lines below this one.
! 441: Then type M-x repl s<Return>changed<Return>altered<Return>.
! 442:
! 443: Notice how this line has changed: you've replaced
! 444: the word c-h-a-n-g-e-d with "altered" wherever it occured
! 445: after the cursor.
! 446:
! 447:
! 448: MODE LINE
! 449: ---------
! 450:
! 451: If Emacs sees that you are typing commands slowly it shows them to you
! 452: at the bottom of the screen in an area called the "echo area." The echo
! 453: area contains the bottom line of the screen. The line immediately above
! 454: it is called the MODE LINE. The mode line says something like
! 455:
! 456: --**-Mg: TUTORIAL (fundamental)------------------------
! 457:
! 458: This is a very useful "information" line.
! 459:
! 460: The stars near the front mean that you have made changes to the text.
! 461: Right after you visit or save a file, there are no stars, just dashes.
! 462:
! 463: The part of the mode line inside the parentheses is to tell you what
! 464: modes you are in. The default mode is fundamental which is what you
! 465: are in now. It is an example of a "mode". There are several modes in
! 466: Emacs for editing different styles of text, such as indent, bsmap,
! 467: fill, etc. Each mode makes a few commands behave differently.
! 468:
! 469: One mode which is very useful, especially for editing English text, is
! 470: Auto Fill mode. When this mode is on, Emacs breaks the line in
! 471: between words automatically whenever the line gets too long. You can
! 472: turn this mode on by doing M-x auto-fill-mode<Return>. When the mode
! 473: is on, you can turn it off by doing M-x auto-fill-mode<Return>.
! 474:
! 475: >> Type M-x auto-fill-mode<Return> now. Then insert a line of "asdf "
! 476: over again until you see it divide into two lines. You must put in
! 477: spaces between them because Auto Fill breaks lines only at spaces.
! 478:
! 479: The margin is usually set at 70 characters, but you can change it
! 480: with the C-x f command. You should give the margin setting you want
! 481: as a numeric argument.
! 482:
! 483: >> Type C-x f with an argument of 20. (C-u 2 0 C-x f).
! 484: Then type in some text and see Emacs fill lines of 20
! 485: characters with it. Then set the margin back to 70 using
! 486: C-x f again.
! 487:
! 488: If you make changes in the middle of a paragraph, Auto Fill mode
! 489: does not re-fill it for you.
! 490: To re-fill the paragraph, type M-q (Meta-q) with the cursor inside
! 491: that paragraph.
! 492:
! 493: >> Move the cursor into the previous paragraph and type M-q.

! 495: SEARCHING
! 496: ---------
! 497:
! 498: Emacs can do searches for strings (these are groups of contiguous
! 499: characters or words) either forward through the file or backward
! 500: through it. To search for the string means that you are trying to
! 501: locate it somewhere in the file and have Emacs show you where the
! 502: occurrences of the string exist. This type of search is somewhat
! 503: different from what you may be familiar with. It is a search that is
! 504: performed as you type in the thing to search for. The command to
! 505: initiate a search is C-s for forward search, and C-r for reverse
! 506: search. BUT WAIT! Don't do them now. When you type C-s you'll
! 507: notice that the string "I-search" appears as a prompt in the echo
! 508: area. This tells you that Emacs is in what is called an incremental
! 509: search waiting for you to type the thing that you want to search for.
! 510: <ESC> terminates a search.
! 511:
! 512: >> Now type C-s to start a search. SLOWLY, one letter at a time,
! 513: type the word 'cursor', pausing after you type each
! 514: character to notice what happens to the cursor.
! 515: >> Type C-s to find the next occurrence of "cursor".
! 516: >> Now type <DEL> four times and see how the cursor moves.
! 517: >> Type <ESC> to terminate the search.
! 518:
! 519: Did you see what happened? Emacs, in an incremental search, tries to
! 520: go to the occurrence of the string that you've typed out so far. To go
! 521: to the next occurrence of 'cursor' just type C-s again. If no such
! 522: occurrence exists Emacs beeps and tells you that it is a failing
! 523: search. C-g would also terminate the search.
! 524:
! 525: If you are in the middle of an incremental search and type <DEL>,
! 526: you'll notice that the last character in the search string is erased
! 527: and the search backs up to the last place of the search. For
! 528: instance, suppose you currently have typed 'cu' and you see that your
! 529: cursor is at the first occurrence of 'cu'. If you now type <DEL>,
! 530: the 'u' on the search line is erased and you'll be repositioned in the
! 531: text to the occurrence of 'c' where the search took you before you
! 532: typed the 'u'. This provides a useful means for backing up while you
! 533: are searching.
! 534:
! 535: If you are in the middle of a search and happen to type a control
! 536: character (other than a C-s or C-r, which tell Emacs to search for the
! 537: next occurrence of the string), the search is terminated.
! 538:
! 539: The C-s starts a search that looks for any occurrence of the search
! 540: string AFTER the current cursor position. But what if you want to
! 541: search for something earlier in the text? To do this, type C-r for
! 542: Reverse search. Everything that applies to C-s applies to C-r except
! 543: that the direction of the search is reversed.

! 546: GETTING MORE HELP
! 547: -----------------
! 548:
! 549: In this tutorial we have tried to supply just enough information to
! 550: get you started using Emacs. There is so much available in Emacs that
! 551: it would be impossible to explain it all here. However, you may want
! 552: to learn more about Emacs since it has numerous desirable features
! 553: that you don't know about yet.
! 554:
! 555:
! 556: CONCLUSION
! 557: ----------
! 558:
! 559: Remember, to exit Emacs permanently use C-x C-c. To exit to a shell
! 560: temporarily, so that you can come back in, use C-z.
! 561:
! 562: This tutorial is meant to be understandable to all new users, so if
! 563: you found something unclear, don't sit and blame yourself - complain!
