I've got Word 2010 and also 2016. Often, for lengthy texts I copy/paste into Word from online plain text documents or from html website sections, I need to do this:

I want to select all blank lines in the doc and then reduce the vertical spacing, above and below of the blank lines (I presume, by reducing the fontsize of the blank lines, or, by reducing the interline spacing for the blank lines?). With "show formatting marks" turned on, a blank line appears as a single paragraph mark by itself. Non-blank lines appear as text followed by the paragraph mark at the end of each line (i.e. from the sources I copy/paste from, Word imports each line as a separate paragraph.)

Using ADVANCED FIND, I can easily select all Paragraph Marks in the doc (which appear at the end of every line, blank or not), but I don't see a way to select only the blank lines paragraphs.

Any help would be GREATLY appreciated.
