If you \fB:se list\fR\s-2CR\s0, -then the end of each line will be shown by printing a \fB$\fR after the -end of the displayed text in the line. Given a count, advances to the -count'th following end of line; thus \fB2$\fR advances to the end of the -following line. -.iP "%" 15 -Moves to the parenthesis or brace \fB{ }\fR which balances the parenthesis -or brace at the current cursor position. -.iP "&" 15 -A synonym for \fB:&\fR\s-2CR\s0, by analogy with the -.I ex -.B & -command. -.iP "\(aa" 15 -When followed by a \fB\(aa\fR returns to the previous context at the -beginning of a line. The previous context is set whenever the current -line is moved in a non-relative way. -When followed by a letter \fBa\fR\-\fBz\fR, returns to the line which -was marked with this letter with a \fBm\fR command, at the first non-white -character in the line. (2.2, 5.3). -When used with an operator such as \fBd\fR, the operation takes place -over complete lines; if you use \fB\(ga\fR, the operation takes place -from the exact marked place to the current cursor position within the -line. -.iP "(" 15 -Retreats to the beginning of a -sentence, or to the beginning of a \s-2LISP\s0 s-expression -if the \fIlisp\fR option is set. -A sentence ends at a \fB. !\fR or \fB?\fR which is followed by either -the end of a line or by two spaces. Any number of closing \fB) ] "\fR -and \fB\(aa\fR characters may appear after the \fB. !\fR or \fB?\fR, -and before the spaces or end of line.

Especially useful after hitting too many \fB;\fR -characters. A count repeats the search. -.iP "\-" 15 -Retreats to the previous line at the first non-white character. -This is the inverse of \fB+\fR and \s-2RETURN\s0. -If the line moved to is not on the screen, the screen is scrolled, or -cleared and redrawn if this is not possible. -If a large amount of scrolling would be required the screen is also cleared -and redrawn, with the current line at the center (2.3). -.iP "\&." 15 -Repeats the last command which changed the buffer. Especially useful -when deleting words or lines; you can delete some words/lines and then -hit \fB.\fR to delete more and more words/lines. -Given a count, it passes it on to the command being repeated. Thus after -a \fB2dw\fR, \fB3.\fR deletes three words (3.3, 6.3, 7.2, 7.4). -.iP "/" 15 -Reads a string from the last line on the screen, and scans forward for -the next occurrence of this string. The normal input editing sequences may -be used during the input on the bottom line; an returns to command state -without ever searching. -The search begins when you hit \s-2CR\s0 to terminate the pattern; -the cursor moves to the beginning of the last line to indicate that the search -is in progress; the search may then -be terminated with a \s-2DEL\s0 or \s-2RUB\s0, or by backspacing when -at the beginning of the bottom line, returning the cursor to -its initial position. -Searches normally wrap end-around to find a string -anywhere in the buffer. -.IP -When used with an operator the enclosed region is normally affected. -By mentioning an -offset from the line matched by the pattern you can force whole lines -to be affected. To do this give a pattern with a closing -a closing \fB/\fR and then an offset \fB+\fR\fIn\fR or \fB\-\fR\fIn\fR. -.IP -To include the character \fB/\fR in the search string, you must escape -it with a preceding \fB\e\fR. -A \fB\(ua\fR at the beginning of the pattern forces the match to occur -at the beginning of a line only; this speeds the search. A \fB$\fR at -the end of the pattern forces the match to occur at the end of a line -only. -More extended pattern matching is available, see section 7.4; -unless you set \fBnomagic\fR in your \fI\&.exrc\fR file you will have -to preceed the characters \fB. [ *\fR and \fB~\fR in the search pattern -with a \fB\e\fR to get them to work as you would naively expect (1.5, 2,2, -6.1, 7.2, 7.4). -.iP "0" 15 -Moves to the first character on the current line. -Also used, in forming numbers, after an initial \fB1\fR\-\fB9\fR. -.iP "1\-9" 15 -Used to form numeric arguments to commands (2.3, 7.2). -.iP ":" 15 -A prefix to a set of commands for file and option manipulation and escapes -to the system. Input is given on the bottom line and terminated with -an \s-2CR\s0, and the command then executed. You can return to where -you were by hitting \s-2DEL\s0 or \s-2RUB\s0 if you hit \fB:\fR accidentally -(see primarily 6.2 and 7.3). -.iP ";" 15 -Repeats the last single character find which used \fBf F t\fR or \fBT\fR. -A count iterates the basic scan (4.1). -.iP "<" 15 -An operator which shifts lines left one \fIshiftwidth\fR, normally 8 -spaces. Like all operators, affects lines when repeated, as in -\fB<<\fR. Counts are passed through to the basic object, thus \fB3<<\fR -shifts three lines (6.6, 7.2). -.iP "=" 15 -Reindents line for \s-2LISP\s0, as though they were typed in with \fIlisp\fR -and \fIautoindent\fR set (6.8). -.iP ">" 15 -An operator which shifts lines right one \fIshiftwidth\fR, normally 8 -spaces. Affects lines when repeated as in \fB>>\fR. Counts repeat the -basic object (6.6, 7.2). -.iP "?" 15 -Scans backwards, the opposite of \fB/\fR. See the \fB/\fR description -above for details on scanning (2.2, 6.1, 7.4). -.iP "@" 15 -A macro character (6.9). If this is your kill character, you must escape it with a \e -to type it in during input mode, as it normally backs over the input you -have given on the current line (3.1, 3.4, 7.5). -.iP "A" 15 -Appends at the end of line, a synonym for \fB$a\fR (7.2). -.iP "B" 15 -Backs up a word, where words are composed of non-blank sequences, placing -the cursor at the beginning of the word. A count repeats the effect -(2.4). -.iP "C" 15 -Changes the rest of the text on the current line; a synonym for \fBc$\fR. -.iP "D" 15 -Deletes the rest of the text on the current line; a synonym for \fBd$\fR. -.iP "E" 15 -Moves forward to the end of a word, defined as blanks and non-blanks, -like \fBB\fR and \fBW\fR. A count repeats the effect. -.iP "F" 15 -Finds a single following character, backwards in the current line. -A count repeats this search that many times (4.1). -.iP "G" 15 -Goes to the line number given as preceding argument, or the end of the -file if no preceding count is given. The screen is redrawn with the -new current line in the center if necessary (7.2). -.iP "H" 15 -.B "Home arrow" . -Homes the cursor to the top line on the screen. If a count is given, -then the cursor is moved to the count'th line on the screen. -In any case the cursor is moved to the first non-white character on the -line. If used as the target of an operator, full lines are affected -(2.3, 3.2). -.iP "I" 15 -Inserts at the beginning of a line; a synonym for \fB\(uai\fR. -.iP "J" 15 -Joins together lines, supplying appropriate white space: one space between -words, two spaces after a \fB.\fR, and no spaces at all if the first -character of the joined on line is \fB)\fR. A count causes that many -lines to be joined rather than the default two (6.5, 7.1f). -.iP "K" 15 -Unused. -.iP "L" 15 -Moves the cursor to the first non-white character of the last line on -the screen. With a count, to the first non-white of the count'th line -from the bottom. Operators affect whole lines when used with \fBL\fR -(2.3). -.iP "M" 15 -Moves the cursor to the middle line on the screen, at the first non-white -position on the line (2.3). -.iP "N" 15 -Scans for the next match of the last pattern given to -\fB/\fR or \fB?\fR, but in the reverse direction; this is the reverse -of \fBn\fR. -.iP "O" 15 -Opens a new line above the current line and inputs text there up to an -\s-2ESC\s0. A count can be used on dumb terminals to specify a number -of lines to be opened; this is generally obsolete, as the \fIslowopen\fR -option works better (3.1). -.iP "P" 15 -Puts the last deleted text back before/above the cursor. The text goes -back as whole lines above the cursor if it was deleted as whole lines. -Otherwise the text is inserted between the characters before and at the -cursor. May be preceded by a named buffer specification \fB"\fR\fIx\fR -to retrieve the contents of the buffer; buffers \fB1\fR\-\fB9\fR contain -deleted material, buffers \fBa\fR\-\fBz\fR are available for general -use (6.3). -.iP "Q" 15 -Quits from \fIvi\fR to \fIex\fR command mode. In this mode, whole lines -form commands, ending with a \s-2RETURN\s0. You can give all the \fB:\fR -commands; the editor supplies the \fB:\fR as a prompt (7.7). -.iP "R" 15 -Replaces characters on the screen with characters you type (overlay fashion). -Terminates with an \s-2ESC\s0. -.iP "S" 15 -Changes whole lines, a synonym for \fBcc\fR. A count substitutes for -that many lines. The lines are saved in the numeric buffers, and erased -on the screen before the substitution begins. -.iP "T" 15 -Takes a single following character, locates the character before the -cursor in the current line, and places the cursor just after that character. -A count repeats the effect. Most useful with operators such as \fBd\fR -(4.1). -.iP "U" 15 -Restores the current line to its state before you started changing it -(3.5). -.iP "V" 15 -Unused. -.iP "W" 15 -Moves forward to the beginning of a word in the current line, -where words are defined as sequences of blank/non-blank characters. -A count repeats the effect (2.4). -.iP "X" 15 -Deletes the character before the cursor. A count repeats the effect, -but only characters on the current line are deleted. -.iP "Y" 15 -Yanks a copy of the current line into the unnamed buffer, to be put back -by a later \fBp\fR or \fBP\fR; a very useful synonym for \fByy\fR. -A count yanks that many lines. May be preceded by a buffer name to put -lines in that buffer (7.4). -.iP "ZZ" 15 -Exits the editor. -(Same as \fB:x\fP\s-2CR\s0.) -If any changes have been made, the buffer is written out to the current file. -Then the editor quits. -.iP "[[" 15 -Backs up to the previous section boundary. A section begins at each -macro in the \fIsections\fR option, -normally a `.NH' or `.SH' and also at lines which which start -with a formfeed \fB^L\fR. Lines beginning with \fB{\fR also stop \fB[[\fR; -this makes it useful for looking backwards, a function at a time, in C -programs. If the option \fIlisp\fR is set, stops at each \fB(\fR at the -beginning of a line, and is thus useful for moving backwards at the top -level \s-2LISP\s0 objects. (4.2, 6.1, 6.6, 7.2). -.iP "\e" 15 -Unused. -.iP "]]" 15 -Forward to a section boundary, see \fB[[\fR for a definition (4.2, 6.1, -6.6, 7.2). -.iP "\(ua" 15 -Moves to the first non-white position on the current line (4.4). -.iP "_" 15 -Unused. -.iP "\(ga" 15 -When followed by a \fB\(ga\fR returns to the previous context. -The previous context is set whenever the current -line is moved in a non-relative way. -When followed by a letter \fBa\fR\-\fBz\fR, returns to the position which -was marked with this letter with a \fBm\fR command. -When used with an operator such as \fBd\fR, the operation takes place -from the exact marked place to the current position within the line; -if you use \fB\(aa\fR, the operation takes place over complete lines -(2.2, 5.3). -.iP "a" 15 -Appends arbitrary text after the current cursor position; the insert -can continue onto multiple lines by using \s-2RETURN\s0 within the insert. -A count causes the inserted text to be replicated, but only if the inserted -text is all on one line. -The insertion terminates with an \s-2ESC\s0 (3.1, 7.2). -.iP "b" 15 -Backs up to the beginning of a word in the current line. A word is a -sequence of alphanumerics, or a sequence of special characters. -A count repeats the effect (2.4). -.iP "c" 15 -An operator which changes the following object, replacing it with the -following input text up to an \s-2ESC\s0. If more than part of a single -line is affected, the text which is changed away is saved in the numeric named -buffers. If only part of the current line is affected, then the last -character to be changed away is marked with a \fB$\fR. -A count causes that many objects to be affected, thus both -\fB3c)\fR and \fBc3)\fR change the following three sentences (7.4). -.iP "d" 15 -An operator which deletes the following object. If more than part of -a line is affected, the text is saved in the numeric buffers. -A count causes that many objects to be affected; thus \fB3dw\fR is the -same as \fBd3w\fR (3.3, 3.4, 4.1, 7.4). -.iP "e" 15 -Advances to the end of the next word, defined as for \fBb\fR and \fBw\fR. -A count repeats the effect (2.4, 3.1). -.iP "f" 15 -Finds the first instance of the next character following the cursor on -the current line. A count repeats the find (4.1). -.iP "g" 15 -Unused. -.sp -Arrow keys -.B h , -.B j , -.B k , -.B l , -and -.B H . -.iP "h" 15 -.B "Left arrow" . -Moves the cursor one character to the left. -Like the other arrow keys, either -.B h , -the -.B "left arrow" -key, or one of the synonyms (\fB^H\fP) has the same effect. -On v2 editors, arrow keys on certain kinds of terminals -(those which send escape sequences, such as vt52, c100, or hp) -cannot be used. -A count repeats the effect (3.1, 7.5). -.iP "i" 15 -Inserts text before the cursor, otherwise like \fBa\fR (7.2). -.iP "j" 15 -.B "Down arrow" . -Moves the cursor one line down in the same column. -If the position does not exist, -.I vi -comes as close as possible to the same column. -Synonyms include -.B ^J -(linefeed) and -.B ^N . -.iP "k" 15 -.B "Up arrow" . -Moves the cursor one line up. -.B ^P -is a synonym. -.iP "l" 15 -.B "Right arrow" . -Moves the cursor one character to the right. -\s-2SPACE\s0 is a synonym. -.iP "m" 15 -Marks the current position of the cursor in the mark register which is -specified by the next character \fBa\fR\-\fBz\fR. Return to this position -or use with an operator using \fB\(ga\fR or \fB\(aa\fR (5.3). -.iP "n" 15 -Repeats the last \fB/\fR or \fB?\fR scanning commands (2.2). -.iP "o" 15 -Opens new lines below the current line; otherwise like \fBO\fR (3.1). -.iP "p" 15 -Puts text after/below the cursor; otherwise like \fBP\fR (6.3). -.iP "q" 15 -Unused. -.iP "r" 15 -Replaces the single character at the cursor with a single character you -type. The new character may be a \s-2RETURN\s0; this is the easiest -way to split lines. A count replaces each of the following count characters -with the single character given; see \fBR\fR above which is the more -usually useful iteration of \fBr\fR (3.2). -.iP "s" 15 -Changes the single character under the cursor to the text which follows -up to an \s-2ESC\s0; given a count, that many characters from the current -line are changed. The last character to be changed is marked with \fB$\fR -as in \fBc\fR (3.2). -.iP "t" 15 -Advances the cursor upto the character before the next character typed. -Most useful with operators such as \fBd\fR and \fBc\fR to delete the -characters up to a following character. You can use \fB.\fR to delete -more if this doesn't delete enough the first time (4.1). -.iP "u" 15 -Undoes the last change made to the current buffer. If repeated, will -alternate between these two states, thus is its own inverse.
