Hi XGP,

Potentially very difficult but if all other text in the document is
uncoloured you could do it with three Find and Replace operations like this
...

In all cases leave the Find and Replace text boxes blank.

1. (a) Click in the Find box, click on Format > Font and select Text Colour
"Automatic"

1. (b) Click in the Replace box, click on Format > Font and check "Hidden"
(or some other attribute that no other text in the document has)

1. (c) Replace All

2. (a) Click in the Find box, click on "No Formatting" then click on Format

previous operation)

2. (b) Click in the Replace box, click on "No Formatting" then click on
Format > Font and select Text Colour Red

2. (c) Replace All

3. (a) Click in the Find box, click on "No Formatting" then click on Format

operation)

3. (b) Click in the Replace box, click on "No Formatting" then click on
Format > Font and UNcheck "Hidden" (or whichever attribute you chose in  the
first operation)

3. (c) Replace All

Enjoy,
