I'm interested in saving time copy-pasting. I copy paste from websites, articles, newspapers, etc, which have different formatting. When I paste it into my word doc, it typically comes up messy because of paragraph space formatting. I'm wondering if there's a shortcut to replace paragraph spaces with line spaces. It sucks having to go to the end of each line in the copypasted text and hit delete to remove the paragraph spaces. Here's a visualization of what I'm talking about. "Pasted" is what appears when I paste something. "Desired Format" is what I want, by replacing paragraph breaks with line spaces.
Update: Oh right, yes, line break with a space. I am also pasting "text only", though I have tried "keep source formatting", and "merge formatting", all of which don't give me the results I want.
