State the functions of special keys.
Use backspace and delete key to make changes 
in the text.
Use arrow and other navigation keys to move 
the cursor in different directions.
Learning Outcome
Moz: Give a suitable name so that you can easily find your file later. 
Tejas names the file t-friends and Jyoti names her file j-friends.
Jyoti: Can we draw some pictures using the paint activity?
Moz: Ok. I am going out of town for a few weeks. I have prepared a 
list of activities for you. Start the activities tomorrow.
