Frequently I highlight and copy from a source (pdf, etc.) and paste into Libre Writer.
Often the source has a LF/CR at the end of each line instead of just at the end of a paragraph. This is because the source did not support a line wrap function so they just hard break at the end of each line.
This means that there are hundreds of paragraph marks in the document, many in the middle of sentences.
I wish to get rid of them using find and replace. This usually means that the paragraph mark is preceded by a lower case letter. So I search for
[a-z]$ and replace with
$0 or ampersand followed by a space. This should substitute a space for a paragraph mark. But it does not work.
When searching for just a paragraph mark
$ Find finds the mark and highlights it.
But when searching for specific cases of paragraph mark like a letter just before a paragraph mark then it only highlights the letter and not also the paragraph mark.
Open Office and Libre both have this weakness. So every time I need to do this type of edit, which is actually quite often, I have to go to a computer with MS Word.
In MS Word I search for
[a-z]^p and it highlights both the letter and the paragraph mark. So the replace works just fine.
