3. Simple changes				*simple-change* *changing*

							*r*
r{char}			Replace the character under the cursor with {char}.
			If {char} is a <CR> or <NL>, a line break replaces the
			character.  To replace with a real <CR>, use CTRL-V
			<CR>.  CTRL-V <NL> replaces with a <Nul>.

			If {char} is CTRL-E or CTRL-Y the character from the
			line below or above is used, just like with |i_CTRL-E|
			and |i_CTRL-Y|.  This also works with a count, thus
			`10r<C-E>` copies 10 characters from the line below.

			If you give a [count], Vim replaces [count] characters
			with [count] {char}s.  When {char} is a <CR> or <NL>,
			however, Vim inserts only one <CR>: "5r<CR>" replaces
			five characters with a single line break.
			When {char} is a <CR> or <NL>, Vim performs
			autoindenting.  This works just like deleting the
			characters that are replaced and then doing
			"i<CR><Esc>".
			{char} can be entered as a digraph |digraph-arg|.
			|:lmap| mappings apply to {char}.  The CTRL-^ command
			in Insert mode can be used to switch this on/off
			|i_CTRL-^|.  See |utf-8-char-arg| about using
			composing characters when 'encoding' is Unicode.

							*gr*
gr{char}		Replace the virtual characters under the cursor with
			{char}.  This replaces in screen space, not file
			space.  See |gR| and |Virtual-Replace-mode| for more
			details.  As with |r| a count may be given.
			{char} can be entered like with |r|, but characters
			that have a special meaning in Insert mode, such as
			most CTRL-keys, cannot be used.

							*gr-default*
			Nvim creates |lsp-defaults| mappings which may inhibit
			the builtin behavior of |gr|. Use this to restore the
			builtin behavior: >
				nnoremap <nowait> gr gr
<

						*digraph-arg*
The argument for Normal mode commands like |r| and |t| is a single character.
When 'cpo' doesn't contain the 'D' flag, this character can also be entered
like |digraphs|.  First type CTRL-K and then the two digraph characters.

						*case*
The following commands change the case of letters.  The currently active
|locale| is used.  See |:language|.  The LC_CTYPE value matters here.

							*~*
~			'notildeop' option: Switch case of the character
			under the cursor and move the cursor to the right.
			If a [count] is given, do that many characters.

~{motion}		'tildeop' option: switch case of {motion} text.

							*g~*
g~{motion}		Switch case of {motion} text.

g~g~							*g~g~* *g~~*
g~~			Switch case of current line.

							*v_~*
{Visual}~		Switch case of highlighted text (for {Visual} see
			|Visual-mode|).

							*v_U*
{Visual}U		Make highlighted text uppercase (for {Visual} see
			|Visual-mode|).

							*gU* *uppercase*
gU{motion}		Make {motion} text uppercase.
			Example: >
				:map! <C-F> <Esc>gUiw`]a
<			This works in Insert mode: press CTRL-F to make the
			word before the cursor uppercase.  Handy to type
			words in lowercase and then make them uppercase.


gUgU							*gUgU* *gUU*
gUU			Make current line uppercase.

							*v_u*
{Visual}u		Make highlighted text lowercase (for {Visual} see
			|Visual-mode|).

							*gu* *lowercase*
gu{motion}		Make {motion} text lowercase.

gugu							*gugu* *guu*
guu			Make current line lowercase.

							*g?* *rot13*
g?{motion}		Rot13 encode {motion} text.

							*v_g?*
{Visual}g?		Rot13 encode the highlighted text (for {Visual} see
			|Visual-mode|).

g?g?							*g?g?* *g??*
g??			Rot13 encode current line.

To turn one line into title caps, make every first letter of a word
uppercase: >
	:s/\v<(.)(\w*)/\u\1\L\2/g


Adding and subtracting ~
							*CTRL-A*
CTRL-A			Add [count] to the number or alphabetic character at
			or after the cursor.

                                                       *v_CTRL-A*
{Visual}CTRL-A		Add [count] to the number or alphabetic character in
			the highlighted text.

							*v_g_CTRL-A*
{Visual}g CTRL-A	Add [count] to the number or alphabetic character in
			the highlighted
