+.SH DESCRIPTION
+.I Vi
+(visual) is a display oriented text editor based on
+.IR ex (1).
+.I Ex
+and
+.I vi
+run the same code; it is possible to get to
+the command mode of
+.I ex
+from within
+.I vi
+and vice-versa.
+.PP
+The
+.I view
+command is identical to
+.I vi
+except that files are opened read-only.
+The
+.I vedit
+command is also identical,
+but sets some options to values more useful for novices.
+.PP
+The following options are accepted:
+.TP
+\fB\-c\fP\fI\ command\fP or \fB+\fP\fIcommand\fP
+Execute
+.I command
+when editing begins.
+.TP
+.B \-l
+Start in a special mode useful for the
+.I Lisp
+programming language.
+.TP
+\fB\-r\fI\ [filename]\fR or \fB\-L\fR
+When no argument is supplied with this option,
+all files to be recovered are listed
+and the editor exits immediately.
+If a
+.I filename
+is specified,
+the corresponding temporary file is opened in recovery mode.
+.TP
+.B \-R
+Files are opened read-only when this option is given.
+.TP
+.BR \-s \ or\  \-
+Script mode;
+all feedback for interactive editing is disabled.
+.SM EXINIT
+and
+.I .exrc
+files are not processed.
+.TP
+.BI \-t \ tagstring
+Read the
+.I tags
+file,
+then choose the file and position specified by
+.I tagstring
+for editing.
+.TP
+.B \-V
+Echo command input to standard error,
+unless it originates from a terminal.
+.TP
+.BI \-w \ size
+Specify the size of the editing window for visual mode.
+.PP
+The
+.I "Introduction to Display Editing with Vi"
+provides full details on using
+.I vi.
+.PP
+Most of the
+.I ex
+commands are available in
+.I visual
+mode when prefixed by a
+.B :
+character. See
+.BR ex (1)
+for a description of them.
+.\"	from vi.chars	8.1 (Berkeley) 6/8/93
+.PP
+The following gives the uses the editor makes of each character.  The
+characters are presented in their order in the \s-1ASCII\s0 character
+set:  Control characters come first, then most special characters, then
+the digits, upper and then lower case characters.
+.PP
+For each character we tell a meaning it has as a command and any meaning it
+has during an insert.
+If it has only meaning as a command, then only this is discussed.
+Section numbers in parentheses indicate where the character is discussed
+in \*(lqAn Introduction to Display Editing with Vi\*(rq;
+a `f' after the section number means that the character is mentioned
+in a footnote.
+.TP
+\fB^@\fR
+Not a command character.
+If typed as the first character of an insertion it is replaced with the
+last text inserted, and the insert terminates.  Only 128 characters are
+saved from the last insert; if more characters were inserted the mechanism
+is not available.
+A \fB^@\fR cannot be part of the file due to the editor implementation
+(7.5f).
+.TP
+\fB^A\fR
+Unused.
+.TP
+\fB^B\fR
+Backward window.
+A count specifies repetition.
+Two lines of continuity are kept if possible (2.1, 6.1, 7.2).
+.TP
+\fB^C\fR
+Unused.
+.TP
+\fB^D\fR
+As a command, scrolls down a half-window of text.  
+A count gives the number of (logical) lines to scroll, and is remembered
+for future \fB^D\fR and \fB^U\fR commands (2.1, 7.2).
+During an insert, backtabs over \fIautoindent\fR white space at the beginning
+of a line (6.6, 7.5); this white space cannot be backspaced over.
+.TP
+\fB^E\fR
+Exposes one more line below the current screen in the file, leaving
+the cursor where it is if possible.
+.TP
+\fB^F\fR
+Forward window.  A count specifies repetition.
+Two lines of continuity are kept if possible (2.1, 6.1, 7.2).
+.TP
+\fB^G\fR
+Equivalent to \fB:f\fR\s-1CR\s0, printing the current file, whether
+it has been modified, the current line number and the number of lines
+in the file, and the percentage of the way through the file.
+.TP
+\fB^H (\fR\s-1BS\s0\fB)\fR
+Same as
+.BR "left arrow" .
+(See
+.BR h ).
+During an insert, eliminates the last input character, backing over it
+but not erasing it; it remains so the user can see what he typed if he
+wishes to type something only slightly different (3.1, 7.5).
+.TP
+\fB^I\ (\fR\s-1TAB\s0\fB)\fR
+Not a command character.
+When inserted it prints as some
+number of spaces.
+When the cursor is at a tab character it rests at the last of the spaces
+which represent the tab.
+The spacing of tabstops is controlled by the \fItabstop\fR option (4.1, 6.6).
+.TP
+\fB^J\ (\fR\s-1LF\s0\fB)\fR
+Same as
+.B "down arrow"
+(see
+.BR j ).
+.TP
+\fB^K\fR
+Unused.
+.TP
+\fB^L\fR
+The \s-1ASCII\s0 formfeed character, this causes the screen to be cleared
+and redrawn.  This is useful after a transmission error, if characters
+typed by a program other than the editor scramble the screen,
+or after output is stopped by an interrupt (5.4, 7.2f).
+.TP
+\fB^M\ (\fR\s-1CR\s0\fB)\fR
+A carriage return advances to the next line, at the first non-white position
+in the line.  Given a count, it advances that many lines (2.3).
+During an insert, a \s-1CR\s0 causes the insert to continue onto
+another line (3.1).
+.TP
+\fB^N\fR
+Same as
+.B "down arrow"
+(see
+.BR j ).
+.TP
+\fB^O\fR
+Unused.
+.TP
+\fB^P\fR
+Same as
+.B "up arrow"
+(see
+.BR k ).
+.TP
+\fB^Q\fR
+Not a command character.
+In input mode,
+.B ^Q
+quotes the next character, the same as
+.B ^V ,
+except that some teletype drivers will eat the
+.B ^Q
+so that the editor never sees it.
+.TP
+\fB^R\fR
+Redraws the current screen, eliminating logical lines not corresponding
+to physical lines (lines with only a single @ character on them).
+On hardcopy terminals in \fIopen\fR mode, retypes the current line
+(5.4, 7.2, 7.8).
+.TP
+\fB^S\fR
+Unused.  Some teletype drivers use
+.B ^S
+to suspend output until
+.B ^Q is pressed.
+.TP
+\fB^T\fR
+Not a command character.
+During an insert, with \fIautoindent\fR set and at the beginning of the
+line, inserts \fIshiftwidth\fR white space.
+.TP
+\fB^U\fR
+Scrolls the screen up, inverting \fB^D\fR which scrolls down.  Counts work as
+they do for \fB^D\fR, and the previous scroll amount is common to both.
+On a dumb terminal, \fB^U\fR will often necessitate clearing and redrawing
+the screen further back in the file (2.1, 7.2).
+.TP
+\fB^V\fR
+Not a command character.
+In input mode, quotes the next character so that it is possible
+to insert non-printing and special characters into the file (4.2, 7.5).
+.TP
+\fB^W\fR
+Not a command character.
+During an insert, backs up as \fBb\fR would in command mode; the deleted
+characters remain on the display (see \fB^H\fR) (7.5).
+.TP
+\fB^X\fR
+Unused.
+.TP
+\fB^Y\fR
+Exposes one more line above the current screen, leaving the cursor where
+it is if possible.  (No mnemonic value for this key; however, it is next
+to \fB^U\fR which scrolls up a bunch.)
+.TP
+\fB^Z\fR
+If supported by the Unix system,
+stops the editor, exiting to the top level shell.
+Same as \fB:stop\fP\s-1CR\s0.
+Otherwise, unused.
+.TP
+\fB^[\ (\fR\s-1ESC\s0\fB)\fR
+Cancels a partially formed command, such as a \fBz\fR when no following
+character has yet been given; terminates inputs on the last line (read
+by commands such as \fB: /\fR and \fB?\fR); ends insertions of new text
+into the buffer.
+If an \s-1ESC\s0 is given when quiescent in command state, the editor
+rings the bell or flashes the screen.  The user can thus hit \s-1ESC\s0 if
+he doesn't know what is happening till the editor rings the bell.
+If the user doesn't know whether he is in insert mode
+he can type \s-1ESC\s0\fBa\fR,
+and then material to be input; the material will be inserted correctly
+whether or not he was in insert mode when he started (1.6, 3.1, 7.5).
+.TP
+\fB^\e\fR
+Unused.
+.TP
+\fB^]\fR
+Searches for the word which is after the cursor as a tag.  Equivalent
+to typing \fB:ta\fR, this word, and then a \s-1CR\s0.
+Mnemonically, this command is \*(lq right to\*(rq (7.3).
+.TP
+\fB^^\fR
+Equivalent to \fB:e #\fR\s-1CR\s0, returning to the previous position
+in the last edited file, or editing a file which the user specified if he
+got a `No write since last change diagnostic' and does not want to have
+to type the file name again (7.3).
+(The user has to do a \fB:w\fR before \fB^^\fR
+will work in this case.  If he does not wish to write the file he should
+do \fB:e!\ #\fR\s-1CR\s0 instead.)
+.TP
+\fB^_\fR
+Unused.
+Reserved as the command character for the
+Tektronix 4025 and 4027 terminal.
+.TP
+\fB\fR\s-1SPACE\s0\fB\fR
+Same as
+.B "right arrow"
+(see
+.BR l ).
+.TP
+\fB!\fR
+An operator, which processes lines from the buffer with reformatting commands.
+Follow \fB!\fR with the object to be processed, and then the command name
+terminated by \s-1CR\s0.  Doubling \fB!\fR and preceding it by a count
+causes count lines to be filtered; otherwise the count
+is passed on to the object after the \fB!\fR.  Thus \fB2!}\fR\fIfmt\fR\s-1CR\s0
+reformats the next two paragraphs by running them through the program
+\fIfmt\fR.  If working on \s-1LISP\s0,
+the command \fB!%\fR\fIgrind\fR\s-1CR\s0,
+.\"*
+.\".FS
+.\"*Both
+.\".I fmt
+.\"and
+.\".I grind
+.\"are Berkeley programs and may not be present at all installations.
+.\".FE
+given at the beginning of a
+function, will run the text of the function through the \s-1LISP\s0 grinder
+(6.7, 7.3).
+To read a file or the output of a command into the buffer \fB:r\fR (7.3)
+can be used.
+To simply execute a command, \fB:!\fR (7.3).
+.tr "
+.iP  15
+Precedes a named buffer specification.  There are named buffers \fB1\-9\fR
+used for saving deleted text and named buffers \fBa\-z\fR into which the
+user can place text (4.3, 6.3)
+.tr 
+.TP
+\fB#\fR
+The macro character which, when followed by a number, will substitute
+for a function key on terminals without function keys (6.9).
+In input mode, 
+if this is the erase character, it will delete the last character
+typed in input mode, and must be preceded with a \fB\e\fR to insert
+it, since it normally backs over the last input character.
+.TP
+\fB$\fR
+Moves to the end of the current line.  If the \fBlist\fR option is set,
+then the end of each line will be shown by printing a \fB$\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.
+.TP
+\fB%\fR
+Moves to the parenthesis or brace \fB{ }\fR which balances the parenthesis
+or brace at the current cursor position.
+.TP
+\fB&\fR
+A synonym for \fB:&\fR\s-1CR\s0, by analogy with the
+.I ex
+.B &
+command.
+.TP
+\fB\(aa\fR
+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 \fB\(ga\fR is used, the operation takes place
+from the exact marked place to the current cursor position within the
+line.
+.TP
+\fB(\fR
+Retreats to the beginning of a
+sentence, or to the beginning of a \s-1LISP\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.  Sentences also begin
+at paragraph and section boundaries
+(see \fB{\fR and \fB[[\fR below).
+A count advances that many sentences (4.2, 6.8).
+.TP
+\fB)\fR
+Advances to the beginning of a sentence.
+A count repeats the effect.
+See \fB(\fR above for the definition of a sentence (4.2, 6.8).
+.TP
+\fB*\fR
+Unused.
+.TP
+\fB+\fR
+Same as \s-1CR\s0 when used as a command.
+.TP
+\fB,\fR
+Reverse of the last \fBf F t\fR or \fBT\fR command, looking the other way
+in the current line.  Especially useful after hitting too many \fB;\fR
+characters.  A count repeats the search.
+.TP
+\fB\-\fR
+Retreats to the previous line at the first non-white character.
+This is the inverse of \fB+\fR and \s-1RETURN\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).
+.TP
+\fB\&.\fR
+Repeats the last command which changed the buffer.  Especially useful
+when deleting words or lines; the user 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).
+.TP
+\fB/\fR
+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 the user hits \s-1CR\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-1DEL\s0 or \s-1RUB\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 the user can force whole lines
+to be affected.  To do this a pattern with a closing
+a closing \fB/\fR and then an offset \fB+\fR\fIn\fR or \fB\-\fR\fIn\fR
+must be given.
+.IP
+To include the character \fB/\fR in the search string, it must be escaped
+with a preceding \fB\e\fR.
+A \fB^\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 \fBnomagic\fR ist set in the \fI\&.exrc\fR file the user 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 one would naively expect (1.6, 2.2,
+6.1, 7.2, 7.4).
+.TP
+\fB0\fR
+Moves to the first character on the current line.
+Also used, in forming numbers, after an initial \fB1\fR\-\fB9\fR.
+.TP
+\fB1\-9\fR
+Used to form numeric arguments to commands (2.3, 7.2).
+.TP
+\fB:\fR
+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-1CR\s0, and the command then executed.  The user can return to where
+he was by hitting \s-1DEL\s0 or \s-1RUB\s0 if he hit \fB:\fR accidentally
+(see 
+.BR ex (1)
+and primarily 6.2 and 7.3).
+.TP
+\fB;\fR
+Repeats the last single character find which used \fBf F t\fR or \fBT\fR.
+A count iterates the basic scan (4.1).
+.TP
+\fB<\fR
+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).
+.TP
+\fB=\fR
+Reindents line for \s-1LISP\s0, as though they were typed in with \fIlisp\fR
+and \fIautoindent\fR set (6.8).
+.TP
+\fB>\fR
+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).
+.TP
+\fB?\fR
+Scans backwards, the opposite of \fB/\fR.  See the \fB/\fR description
+above for details on scanning (2.2, 6.1, 7.4).
+.TP
+\fB@\fR
+A macro character (6.9).  If this is the kill character, it must be escaped
+with a \e
+to type it in during input mode, as it normally backs over the input
+given on the current line (3.1, 3.4, 7.5).
+.TP
+\fBA\fR
+Appends at the end of line, a synonym for \fB$a\fR (7.2).
+.TP
+\fBB\fR
+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).
+.TP
+\fBC\fR
+Changes the rest of the text on the current line; a synonym for \fBc$\fR.
+.TP
+\fBD\fR
+Deletes the rest of the text on the current line; a synonym for \fBd$\fR.
+.TP
+\fBE\fR
+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.
+.TP
+\fBF\fR
+Finds a single following character, backwards in the current line.
+A count repeats this search that many times (4.1).
+.TP
+\fBG\fR
+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).
+.TP
+\fBH\fR
+.BR "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).
+.TP
+\fBI\fR
+Inserts at the beginning of a line; a synonym for \fB^i\fR.
+.TP
+\fBJ\fR
+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).
+.TP
+\fBK\fR
+Unused.
+.TP
+\fBL\fR
+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).
+.TP
+\fBM\fR
+Moves the cursor to the middle line on the screen, at the first non-white
+position on the line (2.3).
+.TP
+\fBN\fR
+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.
+.TP
+\fBO\fR
+Opens a new line above the current line and inputs text there up to an
+\s-1ESC\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).
+.TP
+\fBP\fR
+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).
+.TP
+\fBQ\fR
+Quits from \fIvi\fR to \fIex\fR command mode.  In this mode, whole lines
+form commands, ending with a \s-1RETURN\s0.  One can give all the \fB:\fR
+commands; the editor supplies the \fB:\fR as a prompt (7.7).
+.TP
+\fBR\fR
+Replaces characters on the screen with characters typed (overlay fashion).
+Terminates with an \s-1ESC\s0.
+.TP
+\fBS\fR
+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.
+.TP
+\fBT\fR
+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).
+.TP
+\fBU\fR
+Restores the current line to its state before the user started changing it
+(3.5).
+.TP
+\fBV\fR
+Unused.
+.TP
+\fBW\fR
+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).
+.TP
+\fBX\fR
+Deletes the character before the cursor.  A count repeats the effect,
+but only characters on the current line are deleted.
+.TP
+\fBY\fR
+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).
+.TP
+\fBZZ\fR
+Exits the editor.
+(Same as \fB:x\fP\s-1CR\s0.)
+If any changes have been made, the buffer is written out to the current file.
+Then the editor quits.
+.TP
+\fB[[\fR
+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-1LISP\s0 objects. (4.2, 6.1, 6.6, 7.2).
+.TP
+\fB\e\fR
+Unused.
+.TP
+\fB]]\fR
+Forward to a section boundary, see \fB[[\fR for a definition (4.2, 6.1,
+6.6, 7.2).
+.TP
+\fB^\fR
+Moves to the first non-white position on the current line (4.4).
+.TP
+\fB_\fR
+Unused.
+.TP
+\fB\(ga\fR
+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 using \fB\(aa\fR, the operation takes place over complete lines
+(2.2, 5.3).
+.TP
+\fBa\fR
+Appends arbitrary text after the current cursor position; the insert
+can continue onto multiple lines by using \s-1RETURN\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-1ESC\s0 (3.1, 7.2).
+.TP
+\fBb\fR
+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).
+.TP
+\fBc\fR
+An operator which changes the following object, replacing it with the
+following input text up to an \s-1ESC\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).
+.TP
+\fBd\fR
+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).
+.TP
+\fBe\fR
+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).
+.TP
+\fBf\fR
+Finds the first instance of the next character following the cursor on
+the current line.  A count repeats the find (4.1).
+.TP
+\fBg\fR
+Unused.
+.sp
+Arrow keys
+.BR h ,
+.BR j ,
+.BR k ,
+.BR l ,
+and
+.BR H .
+.TP
+\fBh\fR
+.B "Left arrow" .
+Moves the cursor one character to the left.
+Like the other arrow keys, either
+.BR h ,
+the
+.B "left arrow"
+key, or one of the synonyms (\fB^H\fP) has the same effect.
+A count repeats the effect (3.1, 7.5).
+.TP
+\fBi\fR
+Inserts text before the cursor, otherwise like \fBa\fR (7.2).
+.TP
+\fBj\fR
+.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 .
+.TP
+\fBk\fR
+.B "Up arrow" .
+Moves the cursor one line up.
+.B ^P
+is a synonym.
+.TP
+\fBl\fR
+.B "Right arrow" .
+Moves the cursor one character to the right.
+\s-1SPACE\s0 is a synonym.
+.TP
+\fBm\fR
+Marks the current position of the cursor in the mark register which is
+specified by the next character \fBa\fR\-\fBz\fR.  The user can return
+to this position or use it with an operator
+using \fB\(ga\fR or \fB\(aa\fR (5.3).
+.TP
+\fBn\fR
+Repeats the last \fB/\fR or \fB?\fR scanning commands (2.2).
+.TP
+\fBo\fR
+Opens new lines below the current line; otherwise like \fBO\fR (3.1).
+.TP
+\fBp\fR
+Puts text after/below the cursor; otherwise like \fBP\fR (6.3).
+.TP
+\fBq\fR
+Unused.
+.TP
+\fBr\fR
+Replaces the single character at the cursor with a single character typed.
+The new character may be a \s-1RETURN\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).
+.TP
+\fBs\fR
+Changes the single character under the cursor to the text which follows
+up to an \s-1ESC\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).
+.TP
+\fBt\fR
+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.  One can use \fB.\fR to delete
+more if this doesn't delete enough the first time (4.1).
+.TP
+\fBu\fR
+Undoes the last change made to the current buffer.  If repeated, will
+alternate between these two states, thus is its own inverse. When used
+after an insert which inserted text on more than one line, the lines are
+saved in the numeric named buffers (3.5).
+.TP
+\fBv\fR
+Unused.
+.TP
+\fBw\fR
+Advances to the beginning of the next word, as defined by \fBb\fR (2.4).
+.TP
+\fBx\fR
+Deletes the single character under the cursor.  With a count deletes
+deletes that many characters forward from the cursor position, but only
+on the current line (6.5).
+.TP
+\fBy\fR
+An operator, yanks the following object into the unnamed temporary buffer.
+If preceded by a named buffer specification, \fB"\fR\fIx\fR, the text
+is placed in that buffer also.  Text can be recovered by a later \fBp\fR
+or \fBP\fR (7.4).
+.TP
+\fBz\fR
+Redraws the screen with the current line placed as specified by the following
+character: \s-1RETURN\s0 specifies the top of the screen, \fB.\fR the
+center of the screen, and \fB\-\fR at the bottom of the screen.
+A count may be given after the \fBz\fR and before the following character
+to specify the new screen size for the redraw.
+A count before the \fBz\fR gives the number of the line to place in the
+center of the screen instead of the default current line. (5.4)
+.TP
+\fB{\fR
+Retreats to the beginning of the beginning of the preceding paragraph.
+A paragraph begins at each macro in the \fIparagraphs\fR option, normally
+`.IP', `.LP', `.PP', `.QP' and `.bp'.
+A paragraph also begins after a completely
+empty line, and at each section boundary (see \fB[[\fR above) (4.2, 6.8,
+7.6).
+.TP
+\fB|\fR
+Places the cursor on the character in the column specified
+by the count (7.1, 7.2).
+.TP
+\fB}\fR
+Advances to the beginning of the next paragraph.  See \fB{\fR for the
+definition of paragraph (4.2, 6.8, 7.6).
+.TP
+\fB~\fR
+Switches the case of the given count of characters
+starting from the current cursor position to the end of the current line.
+Non-alphabetic characters remain unchanged.
+.TP
+\fB^?\ (\s-1\fRDEL\fB\s0)\fR
+Interrupts the editor, returning it to command accepting state (1.6,
+7.5).

+William Joy.
+.PP
+Mark Horton added macros to
+.I visual
+mode and was maintaining version 3.
+.PP
+This version incorporates changes by Gunnar Ritter.
+.SH NOTES
+Software tabs using \fB^T\fP work only immediately after the
+.I autoindent.
+.PP
+Left and right shifts on intelligent terminals don't make use of
+insert and delete character operations in the terminal.
+.PP
+The
+.I wrapmargin
+option can be fooled since it looks at output columns when blanks are typed.
+If a long word passes through the margin and onto the next line without a 
+break, then the line won't be broken.
+.PP
+Insert/delete within a line can be slow if tabs are present on intelligent
+terminals, since the terminals need help in doing this correctly.
+.\".PP
+.\"Saving text on deletes in the named buffers is somewhat inefficient.
+.PP
+The
+.I source
+command does not work when executed as \fB:source\fP;
+there is no way to use the \fB:append\fP, \fB:change\fP,
+and \fB:insert\fP commands, since it is not possible to give
+more than one line of input to a \fB:\fP escape.  To use these
+on a \fB:global\fP one must \fBQ\fP to \fIex\fP command mode,
+execute them, and then reenter the screen editor with
+.I vi
+or
+.I open.
