Windows 10. Word 2013.
The following happened:
Somehow the 'Track Changes' menu was turned on and changes which I had made began to appear in red with a line under them.
In the 'Track Changes Menu there are two options: 'Track Changes', and 'Lock Changes'.
I selected 'lock changes' and deleted the text which showed in red and then re-entered the correction.
Now the red text with underlining no longer appears.
However on the left margin of the document there is a vertical line showing where the correction had been made. How do I get rid of this line (which appears in left margin adjacent to where changes have been made).
