%% TIPS %%

 * If we use :set line-cmd, it will display all the option
   which have value other than the default value are displayed.

 * To revert a option back to its default value, we can use:
      :set <option>&

 * To open and edit a file, while the vim is already running,
   we can use:
      :e <filename>
 
 * To see the full path of the current working file in vim, we
   can use <num> + CTRL + g.

      where <num> > 0. 

 * To list all the option we can use to set in .vimrc file can done
   using:

      :h option-list

      Note: There are total 379 option that we can set.

      Another way to view the option is by using:

      :option


* To get to know about different type of color-scheme
  we can use:

  :color<space> + CTRL + d

* After downloading the colorscheme.

  We can put it in the directory:

  /home/<user>/.vim/colors -> Linux
  /Users/<user>/.vim/colors -> Mac


* To map some keystrokes with a particular key (Just like a snippet)

  we use:

  map <KEY> <KEYSTROKES>


* To execute a command written in a file.

  we will use:

  :source <filename>

  For ex:

  :source .vimrc


* Vim has lot of Key-binding having a specific command to execute.

  To define a namespace kind of a thing for specific key-binding
  to execute certain commands we can use mapleader concept.

  By default mapleader key is "\"

  This can be changed by using
  let mapleader="<key>"


  then using it like

  map <leader>w :w!<CR>

  map <leader>key <keystrokes>

  To see the current mapping of keys we can use command:

  :mapping
