gE			Backward to the end of WORD [count] (inclusive).

These commands move over words or WORDS.
							*word*
A word consists of a sequence of letters, digits and underscores, or a
sequence of other non-blank characters, separated with white space (spaces,
tabs, <EOL>).  This can be changed with the 'iskeyword' option.
							*WORD*
A WORD consists of a sequence of non-blank characters, separated with white
space.  An empty line is also considered to be a word and a WORD.

Special case: "cw" and "cW" are treated like "ce" and "cE" if the cursor is
on a non-blank.  This is because "cw" is interpreted as change-word, and a
word does not include the following white space.  {Vi: "cw" when on a blank
followed by other blanks changes only the first blank; this is probably a
bug, because "dw" deletes all the blanks}

Another special case: When using the "w" motion in combination with an
operator and the last word moved over is at the end of a line, the end of
that word becomes the end of the operated text, not the first word in the
next line.

The original Vi implementation of "e" is buggy.  For example, the "e" command
will stop on the first character of a line if the previous line was empty.
But when you use "2e" this does not happen.  In Vim "ee" and "2e" are the
same, which is more logical.  However, this causes a small incompatibility
between Vi and Vim.

5. Text object motions					*object-motions*

							*(*
(			[count] sentences backward (exclusive).

							*)*
)			[count] sentences forward (exclusive).

							*{*
{			[count] paragraphs backward (exclusive).

							*}*
}			[count] paragraphs forward (exclusive).

							*]]*
]]			[count] sections forward or to the next '{' in the
			first column.  When used after an operator, then the
			'}' in the first column.  (linewise).

							*][*
][			[count] sections forward or to the next '}' in the
			first column (linewise).

							*[[*
[[			[count] sections backward or to the previous '{' in
			the first column (linewise).

							*[]*
[]			[count] sections backward or to the previous '}' in
			the first column (linewise).

These commands move over three kinds of text objects.

							*sentence*
A sentence is defined as ending at a '.', '!' or '?' followed by either the
end of a line, or by a space or tab.  Any number of closing ')', ']', '"'
and ''' characters my appear after the '.', '!' or '?' before the spaces,
tabs or end of line.  A paragraph and section boundary is also a sentence
boundary.
If the 'J' flag is present is 'cpoptions', at least two spaces have to
follow the punctuation mark; <Tab>s are not recognized as white space.
The definition of a sentence cannot be changed.

							*paragraph*
A paragraph begins after each empty line, and also at each of a set of
paragraph macros, specified by the pairs of characters in the 'paragraphs'
option.  The default is "IPLPPPQPP LIpplpipbp", which corresponds to the
macros ".IP", ".LP", etc.  (These are nroff macros, so the dot must be in the
first column).  A section boundary is also a paragraph boundary.  Note that
this does not include a '{' or '}' in the first column.  Also note that a
blank line (only containing white space) is NOT a paragraph boundary.

							*section*
A section begins after a form-feed (<C-L>) in the first column and at each of
a set of section macros, specified by the pairs of characters in the
'sections' option.  The default is "SHNHH HUnhsh", which defines a section to
start at the nroff macros ".SH", ".NH", ".H", ".HU", ".nh" and ".sh".

The "]" and "[" commands stop at the '{' or '}' in the first column.  This is
useful to find the start or end of a function in a C program.  Note that the
first character of the command determines the search direction and the
second character the type of brace found.

If your '{' or '}' are not in the first column, and you would like to use "[["
and "]]" anyway, try these mappings:
>  :map [[ ?{<CR>w99[{
>  :map ][ /}<CR>b99]}
>  :map ]] j0[[%/{<CR>
>  :map [] k$][%?}<CR>
[type these literally, see |<>|]

6. Text object selection			*object-select* *text-objects*
						*v_a* *v_i*

This is a series of commands that can only be used while in Visual mode or
after an operator.  The commands that start with "a" select "a"n object
including white space, the commands starting with "i" select an "inner" object
without white space, or just the white space.  Thus the "inner" commands
always select less text than the "a" commands.

These commands are {not in Vi}.
These commands are not available when the |+textobjects| feature has been
disabled at compile time.
							*v_aw*
aw			"a word", select [count] words (see |word|).
			Leading or trailing white space is included, but not
			counted.

							*v_iw*
iw			"inner word", select [count] words (see |word|).
			White space between words is counted too.

							*v_aW*
aW			"a WORD", select [count] WORDs (see |WORD|).
			Leading or trailing white space is included, but not
			counted.

							*v_iW*
iW			"inner WORD", select [count] WORDs (see |WORD|).
			White space between words is counted too.

							*v_as*
as			"a sentence", select [count] sentences (see
			|sentence|).

							*v_is*
is			"inner sentence", select [count] sentences (see
			|sentence|).

							*v_ap*
ap			"a paragraph", select [count] paragraphs (see
			|paragraph|).

							*v_ip*
ip			"inner paragraph", select [count] paragraphs (see
			|paragraph|).

a]							*v_a]* *v_a[*
a[			"a [] block", select [count] '[' ']' blocks.  This
			goes backwards to the [count] unclosed '[', and finds
			the matching ']'.  The enclosed text is selected,
			including the '[' and ']'.

i]							*v_i]* *v_i[*
i[			"inner [] block", select [count] '[' ']' blocks.  This
			goes backwards to the [count] unclosed '[', and finds
			the matching ']'.  The enclosed text is selected,
			excluding the '[' and ']'.

a)							*v_a)*
a(							*v_ab* *v_a(*
ab			"a block", select [count] blocks, from "[count] [(" to
			the matching ')', including the '(' and ')' (see
			|[(|).

i)							*v_i)*
i(							*v_ib* *v_i(*
ib			"inner block", select [count] blocks, from "[count] [("
			to the matching ')', excluding the '(' and ')' (see
			|[(|).

a>							*v_a>* *v_a<*
a<			"a <> block", select [count] <> blocks, from the
			[count]'th unmatched '<' backwards to the matching
			'>', including the '<' and '>'.

i>							*v_i>* *v_i<*
i<			"inner <> block", select [count] <> blocks, from
			the [count]'th unmatched '<' backwards to the matching
			'>', excluding the '<' and '>'.

a}							*v_a}*
a{							*v_aB* *v_a{*
aB			"a Block", select [count] Blocks, from "[count] [{" to
			the matching '}', including the '{' and '}' (see
			|[{|).

i}							*v_i}*
i{							*v_iB* *v_i{*
iB			"inner Block", select [count] Blocks, from "[count] [{"
			to the matching '}', excluding the '{' and '}' (see
			|[{|).

When used after an operator:
For non-block objects:
	For the "a" commands: The operator applies to the object and the white
	space after the object.  If there is no white space after the object
	or when the cursor was in the white space before the object, the white
	space before the object is included.
	For the "inner" commands: If the cursor was on the object, the
	operator applies to the object.  If the cursor was on white space, the
	operator applies to the white space.
For a block object:
	The operator applies to the block where the cursor is in, or the block
	on which the cursor is on one of the braces.  For the "inner" commands
	the surrounding braces are excluded.  For the "a" commands, the braces
	are included.

When used in Visual mode:
When start and end of the Visual area are the same (just after typing "v"):
	One object is selected, the same as for using an operator.
When start and end of the Visual area are not the same:
	For non-block objects the area is extended by one object or the white
	space up to the next object, or both for the "a" objects.  The
	direction in which this happens depends on which side of the Visual
	area the cursor is.  For the block objects the block is extended one
	level outwards.

For illustration, here is a list of delete commands, grouped from small to big
objects.  Note that for a single character and a whole line the existing vi
movement commands are used.
	"dl"	delete character (alias: "x")		|dl|
	"diw"	delete inner word			*diw*
	"daw"	delete a word				*daw*
	"diW"	delete inner WORD (see |WORD|)		*diW*
	"daW"	delete a WORD (see |WORD|)		*daW*
	"dd"	delete one line				|dd|
	"dis"	delete inner sentence			*dis*
	"das"	delete a sentence			*das*
	"dib"	delete inner '(' ')' block		*dib*
	"dab"	delete a '(' ')' block			*dab*
	"dip"	delete inner paragraph			*dip*
	"dap"	delete a paragraph			*dap*
	"diB"	delete inner '{' '}' block		*diB*
	"daB"	delete a '{' '}' block			*daB*

Note the difference between using a movement command and an object.  The
movement command operates from here (cursor position) to where the movement
takes us.  When using an object the whole object is operated upon, no matter
where on the object the cursor is.  For example, compare "dw" and "da": "dw"
deletes from the cursor position to the start of the next word, "da" deletes
the word under the cursor and the space after or before it.

7. Various motions				*various-motions*

						*m* *mark* *Mark*
m{a-zA-Z}		Set mark {a-zA-Z} at cursor position (does not move
			the cursor, this is not a motion command).

m'  or  m`		Set the previous context mark.  This can be jumped to
			with the "''" or "``" command (does not move the
			cursor, this is not a motion command).

						*:ma* *:mark*
:[range]ma[rk] {a-zA-Z}	Set mark {a-zA-Z} at last line number in [range],
			column 0.  Default is cursor line.

						*:k*
:[range]k{a-zA-Z}	Same as :mark, but the space before the mark name can
			be omitted.

						*'* *'a*
'{a-z}			To the first non-blank character on the line with
			mark {a-z} (linewise).
						*'A* *'0*
'{A-Z0-9}		To the first non-blank character on the line with
			mark {A-Z0-9} in the correct file (linewise when in
			same file, not a motion command when in other file).
			{not in Vi}

						*`* *`a*
`{a-z}			To the mark {a-z} (exclusive).
						*`A* *`0*
`{A-Z0-9}		To the mark {A-Z0-9} in the correct file (exclusive
			when in same file, not a motion command when in
			other file).  {not in Vi}

						*:marks*
:marks			List all the current marks (not a motion command).
			{not in Vi}

:marks {arg}		List the marks that are mentioned in {arg} (not a
			motion command).  For example:
>				:marks aB
			to list marks 'a' and 'B'.  {not in Vi}

A mark is not visible in any way.  It is just a position in the file that is
remembered.  Do not confuse marks with named registers, they are totally
unrelated.

'a - 'z		lowercase marks, valid within one file
'A - 'Z		uppercase marks, also called file marks, valid between files
'0 - '9		numbered marks, set from .viminfo file
