My number two wish is a switch that says:
Anything pasted into this document will adopt the formatting of the line into which it is being pasted.
I cannot think of a single instance, ever, when I wanted the formatting from some web page to be carried over into my document.
In Word 2010, try File | Options | Advanced | Cut, copy, and paste | Pasting from other programs: Keep Text Only
If you are using styles, your pasted text will adopt the style of the surrounding paragraph. There are also options for handling pasting within the same document, pasting between documents, and pasting between documents when the style definitions conflict.
