Chandrashekar,
I'm not at the office right now and I don't have that version (or a similar one) at home. I'm not used to using this version of the program (I mostly use the good old V3.0), and if I use it, I do it in German, but I figure you're using the English language. I'll check the right procedure in English tomorrow in the office. I hope this will do for you.
For now I can only guess it's the second menu item from the left once you're in the program and then scroll down to 'Edit'.
Kind regards,
