+-> Text Objects and Macros:
+	
+	**** Text Objects ****
+	@ Command: {operator}{a}{object}
 		
+		What does it do?
+		
+		It perform operation on a word, from the starting character of the word, eventhough the
+		cursor maybe present in the middle of the same word.
+		It will also perform perform operation on the space after that word until a new or a character is
+		encountered.
+
+		For ex:
+
+		daw = Delete A Word
+
+	@ Command: {operator}{i}{object}
+
+		What does it do?
+
+		It perform operation on a word, from the starting charcter of the word, eventhough the cursor
+		maybe present in the middle of the same word.
+		However, unlike {a} operator, it will not perform operation on the space after the word to
+		be deleted.
+
+		For ex:
+	
+		ciw = Change Inner Word.	
+	
+	@ Command: {operator}{as}
+
+		For ex:
+
+		das = Delete a Sentence
+
+		What does it do?
+
+		It will delete a sentence until the period, including the space after the period
+		until the next character is encountered.
+
+	@ Command: {operator}{is}
+
+		For ex:
+
+		dis: Delete inner Sentence
+
+		What does it do?
+
+		It wil delete a sentence until the period, but the space after the period.
+		
+		Note:
+
+		Vim consider line-break as part of the sentence.
+
+	%% TIPS %%
+
+	To repeate these command we can use "." command.
+
+
+	@ Command: {operator}{ap}
+
+		For ex:
+
+		dap = Delete a paragraph
+
+		What does it do?
+
+		It will delete a paragraph until the boundary of the paragraph object,
+		including the blank line.
+
+	@ Command: {operator}{ip}
+
+		For ex:
+
+		dip = Delete a paragraph
+
+		What does it do?
+
+		It will delete a paragraph until the boundary of the paragraph object,
+		i.e. the blank line. However, it does not include the blank line.
+
+
+
+	@ Command: {operator}{a<symbol>} and {operator}{i<symbol>}
+		
+		<symbol>
+
+		{ } or B, ( ) or b, < >, ' ', " ", [ ],` `  
+		For ex:
+
+		di{ or di}
+
+		What does it do?
+
+		It will delete anything between { }. With "a" operator
+		will also delete the { }.
+
+		dab or da( or da)
+
+		What does it do?
+
+		It will delete anything between ( ) including the brackets.
+
+
+		%% TIPS %%
+
+		This command is benificial for programming languages.
+
+		
+		at and it
+
+		t here means tags.
+
+		It will helpful for programming languages with opening
+		and closing tags like html and xml.
+
+		Even custom made tags are applicable in this case.
+
+		 
+	**** Macros ****
+
+	Macros are recorded to a register of vim. (named register)
+
+	%% To recored a macro %%
+
+	Use command: q<register-name>
+
+	It will start the recording.
+
+	Recording ends by using only the command "q".
+
+	%% To use the recorded macro %%
+
+	Use Command: @<register-name>
+
+	%% To use last recorded macro %%
+
+	Use command: @@
+
+	
+	Macro Best Practices
+	--------------------
+
+	* Normalize the cursor position
+		-> 0
+
+	* Perform edits and operations.
+
+	* Position you cursor to enable easy replays.
+		-> j
+
+	%% TIPS %%
+
+	After recording macros to certain register, we can again append to
+	more macros to the register by using q+<Capital-register>.
+	For ex:
+
+	q+A instead of q+a.
+
+
+	This is true for appending anything to the register.	
+
+
+	Applying Macros of particular register on the range of line:
+	------------------------------------------------------------
+	
+	Use command:
+
+	:<start-line-number>,<end-line-number>normal @<register-name>
+
+	From all the line the file.
+
+
+	Use command:
+
+	:.,$normal @<register-name>
+
+	Saving Macros
+	---------------
+
+	* viminfo file
+
+		+ .viminfo ( for unix like system like LINUX or MAC )
+		+ _viminfo ( for windows like system )
+	* Stores history and non-empty registers.
+	* Read when vim starts.
+	* Can easily overwrite registers.
+
+	* vimrc files
+
+		+ .vimrc
+		+ _vimrc
+
+	We can define macros in register inside vimrc file.
+
+	let @<register-name> = '<Marcro>'
+
+	%% TIPS %%
+
+	To know the character of certain key-stroke, like Esc character.
+
+	We can know this by being in insert mode then type CTRL+v and the
+	Key for which we want to know the character.
+
+
+-> Visual mode:
+
+
+	Use v to start characterwise visual mode.
+	Use V to start linewise visual mode.
+	Use Ctrl-v to start blockwise visual mode.
+
+	You can use motions to expand the visual area.
+	You can also use text objects to expand the visual area.
+
+	Just some of commands you can use in visual mode include:
+	~ - Switch case
+	c - Change
+	d - Delete
+	y - Yank
+	r - Replace
+	x - Delete
+	I - Insert
+	A - Append
+	J - Join
+	u - Make lowercase
+	U - Make uppercase
+	> - Shift right
+	< - Shift left
+	o - To move to the end of the highlighted part in the visual mode.
+	O - To move the opposite corner of the highlighted block diagonally.
+	gv - Will highlight everything which it got highlighted last time
+	     and it will position the cursor in the last location where
+	     it was present in visual mode and the mode will also the 
+	     same visual mode which was used last time.
+
+	%% TIPS %%
+
+	To add same character or set of character to multiple lines, use VISUAL-BLOCK
+	mode.
+
+	Go to VISUAL-BLOCK mode select the block, then use INSERT or APPEND, then 
+	add the desired character or set of character and Esc. All the character will
+	appear on desired places.
+	Note: 'i' and 'a' command don't work in VISUAL mode.
+
+	To shift a line without using visual mode, we can use ">>" or "<<" command.
+
+	%% TIPS %%
+
+	To the Shift width and tabs space it applies, we can use:
+	
+	Command: 
+	
+	:set shiftwidth?
+	:set tabstop?
+
+	To identify tab, use ":set list" and the symbol with ^I character represent
+	tab.
+
+	---------------------------
+
+	If shiftwidth = 8 and tabstop = 8 and expandtab is set to noexpandtab,
+	then shift operation is equivalent to tab.
+	expandtab expands with appropiate number of spaces instead of actual
+	tab character.
+
+	
+
+	--------------------
+
+	In visual mode, if we select certain part and use line command to 
+	execute line commmand like ":s/<old>/<new>/" substitution command
+	we can get the range of the highlighted text automatically in form
+	":'<,'>" and we can use it with any line command.
+
+	For ex:
+
+	":'<,'>center"
+
+	This will move highlighted text to the center.
+
+	":'<,'>center 40"
+	
+	Here, 40 is the space count to move it to the center.
+
+	center -> center aligned. (ce)
+	left   -> left aligned. (le)
+	right  -> right aligned. (ri)
+
+	We can use short-hand version as well.
