Hi Nadia!
This is what I found on the internet about "redline" which commonly appears as "redline/strikeout". I believe it is just another way of saying control de cambios in Microsoft Word. Here are some links:

Redline/Strikeout Instructions in Word 1. Open the file in Word. 2. On the
Tools menu, place cursor on
Track Changes, then click on Highlight Changes. 3. A Highlight Changes box will appear, and check all boxes. Then click "OK". 4. As changes are made, redlines and strikeouts will appear in the document.
Hope it helps!
