- Keep Source Formatting
- Merge Formatting
- Keep Text Only
The first option makes plenty of sense to me, the other two behave in ways that may belie their names. Here’s what they really do.
We’ll start with this text.
Keep Source Formatting will keep the original formatting of your copied text and change the target text if you paste inside the paragraph.
Merge Formatting keeps some of the copied text’s formatting, but doesn’t change the original, target. Microsoft says (http://office.microsoft.com/en-us/word-help/paste-options-HA101831692.aspx) that it changes the formatting so that it matches the text that surrounds it. Well, kinda. Here is the results of my test
Keep Text Only is the one I use the most. It actually does what merge formatting seems to describe. The copied text will lose all its original formatting and adopt the formatting of the target text. It’s the one I use the most because I’m usually copying text from a document whose formatting served that document’s purpose, but not the one I’m now creating.
