Thank you so much!
I was worried that there was something very weird going on. I am writing a document under a time limit and I was concerned that this formatting issue might not be easily solved. No idea what these track changes are all about. Recently I have made these stray key hits and all of a sudden there was this gold text that I did not know how to get rid of it. I thought it might be the highlight color, but then changing that did not solve the problem. Perhaps as an update to LibreOffice they could show all text formatting on the text format bar (? or whatever it is called) so at least then you could have a button that you could try to turn off unwanted formatting. I had no idea that there were track changes; I don’t even know what track changes are. Without this forum I would have been stuck.
It would be very helpful if LibreOffice had an overall return to default keypad option. There was no obvious way that LibreOffice would allow me to undo the track changes. When I pushed edit undo this did not reverse the track change. With a complex program such as LibreOffice there are probably other ways that a user might be able to irreversibly change an unknown setting by mistake.
Thank you!
