Hi, Paul is asking if you are using a userform, I believe.

• Create & Employ a Userform by Greg Maxey, MVP
• Create a Simple Userform by Graham Mayor, MVP

You implied that you were. That is likely easier and more elegant than content controls.

For lengthy or highly formatted text, I recommend using AutoText as storage for what you want and inserting the AutoText rather than directly inserting text. I do not recommend hiding/unhiding parts.
