-.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).

-.SH AUTHOR
-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.
