Can't delete a line in a writer file

In a writer document suddenly a line across the page popped up and I can’t delete it.

The ideas of

Writer adds line breaks after comment in doc file

I mostly work with .doc files in LibreOffice Writer V 4.0.4.2 (for reasons of inter-operability - the files have to run on different computers). When I add a comment, writer adds a line break after the space where the comment is located between saving/closing and reloading the document. This didn’t happen in the 3.x versions, if my memory serves correctly. Is there any way to rectify this so I don’t have to delete the extra lines manually?

Undoing / deleting "horizontal line" in writer

I had a problem undoing or deleting a “horizontal line” that I inserted in a document. I found out a way : position on the line and modify the layout of the paragraph : it was been marked as having a border on the bottom. just indicate no borders and it is OK

did not lead to the needed solution.

How can this line be deleted?

Thanks for helping comments

There are a couple of ways to remove the line if it is the Horizontal Line:

• Click at the end of the previous paragraph before the line and press Del . Or
• Click at the beginning of the line and double click the paragraph style you want in the Styles sidebar. You could instead press Ctrl+0 (zero) to change the paragraph style of the horizontal line to Body Text

a line across the page popped up

Near some text? Could it be a paragraph border?
In the middle of the page?
Hard to guess withou seeing.

Is a line inserted with menu Horizontal line?
Is this line inserted near the TOC?

The usual way to erase a line is to place in the paragraph before the line and use the Supr key.
If this Horizontal line is just after the Table of Contents, you must unprotect the TOC before to delete the line.

@bantoniof

the Supr key.

The Del key (in English keyboards).
