Thanks Gary-NZStocked. That was really helpful, now I can use the features of bold and italic. Regarding shipping, I want my shipping template to look like in the image below but I somehow, I cannot make my shipping template look like that. Any suggestions please?  

Thank you all for the valuable information. Just wondering, how do you make listing description bold? Is there any feature for that in 'My Products?What is the proper way to change shipping template? Does it make difference going from 'Fres Shipping' to proper shipping template?
