As you use InDesign, you will at some point have to use information that you have in Word or other applications. You may want to bring the format of the source document into InDesign. This is usually the case when you need to do a layout that was already created in Word or another application. There may also be cases where you want the information, but you do not need the formatting to affect your current InDesign document. In this case, you would paste without any formatting from the source document.
You will notice that the option to paste in InDesign with formatting is grayed out. You will need to know how to fix that. It is important to know how to copy from Word to InDesign with or without formatting. This will make working in InDesign and getting information from Word or other applications much easier.
