+%% 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
