				and press this command.

	Note: Anything between [] in help documentation means it is optional in vim.


	For autocompleting a command which is to be searched in help documentation
	click CTRL+D, which shows suggestation. To iterate through all the suggestion
	without writing it explicity use <TAB> key. To iterate in reverse order use
	<SHIFT>+<TAB>.


-> Cut, Copy and Paste:

	* d and x cut text, not just delete it.
	* cut = delete and save into a register.
	* Register is a clipboard-like storage location.
	* This register is also known as default register or unnamed register.
	
	> for pasting the text present in the default register use p command.
	> if the line is cut using dd command then using 'p' will paste it below the current line where
	  the cursor is present.
	> if 'P' command is used then it will paste above the current line where the cursor is
	  present.
	> if a character is cut using 'x' or 'X' command using 'p' will paste the character
	  just after the current postion of the cursor.
	> similarly, if 'P' command is used it will paste the character just before the current
	  position of the cursor.
	
	Note:
		 > The data cutted is linewise then it will paste below/above current line.
		 > The data cutted is characterwise then it will paste before or after the current line.

	> Standard - Vim terminology:

		Cut = Delete
		Copy = yank
		paste = put

	> for yanking(copying) use 'y' or 'Y' command.
