Applying a Paragraph Style to Multiple Paragraphs Non-Destructively

Maris needs to apply styles to the paragraphs in a document that she inherited. When she places the insertion point in a paragraph, she can apply a paragraph style and any explicit character formatting remains intact. If she selects multiple paragraphs at once and applies the paragraph style, then most of the time any explicit character formatting is removed. This means she needs to deal with each paragraph in the document individually, which is tedious. She wonders if there is a quick way to apply a desired paragraph style to a selection of paragraphs without disturbing any explicit character formatting.

The reason that Maris doesn't notice this behavior for all paragraphs is due to the way that Word applies paragraph styles. Whether explicit character formatting is removed or not depends on how many characters are explicitly formatted.

Let's say that you have a paragraph that has 100 characters in it. If more than half of the characters are formatted with the same explicit character format, then that formatting is removed when you apply the paragraph style. For instance, if over half of the paragraph is formatted in bold, then the bold will be removed when the style is applied.

This "50% rule" doesn't apply if there is a mix of explicit formatting. For instance, in the same 100-character paragraph, if 25 characters are explicitly bold, 25 are explicitly italic, and 25 are explicitly underlined, the "50% rule" hasn't been met because no single explicit format is over the 50%. So, the explicit formatting survives the application of the new paragraph style.

There are two ways that you can get around the issue. The first is to use Find and Replace:

1. Select the paragraphs you want to affect.
2. Press Ctrl+H. Word displays the Replace tab of the Find and Replace dialog box.
3. Click the More button if it is available.
4. Make sure the Find What and Replace With boxes are empty.
5. With the insertion point in the Find What box, click Format | Style. Word displays the Find Style dialog box.
6. Choose the style you want to replace and then click OK.
7. With the insertion point in the Replace With box, click Format | Style. Word displays the Replace Style dialog box.
8. Choose the style you want to replace and then click OK.
9. Click Replace All. Word indicates how many changes were made; click OK.
10. Dismiss the Find and Replace dialog box.

While this approach doesn't destroy any explicit formatting, it will remove any explicit paragraph formatting. Thus, if one of the paragraphs has explicit indents applied, then those indents are removed when the new style is applied.

The second way you can get around this issue is to simply not use explicit character formatting. Instead, define character styles for all of your character formatting needs, and then apply those to the characters in the paragraphs. In this approach, the "50% rule" isn't followed at all as the character styles are not removed when you apply a new paragraph style.
