I use Libreoffice to compose tests for my classes. I use the numbering facility to number the questions. I have to leave blank lines between questions so that the students have room to write their answers. I do this by typing shift-enter several times. This works fine until I try to paste in some questions from another file. When I do that, the numbering ceases to be consecutive. If I try to correct that by turning numbering off and back on, as suggested in the documents, it then numbers every line, not every question. Right now I have a file containing lots of questions that I’d like to choose from to make a test. I can make then numbered consecutively by using Format>>Bullets and Numbering …>> Options and typing into the start-at field.The problem with this is that I have several lists in the file, and they are numbered separately, despite the correct appearance of the pages. If I remove a question from an early list, the following lists don’t renumber themselves to accommodate that. Is there a way to make one list out of these separate ones without numbering all the intervening lines that are not supposed to be numbered.
For the paragraph style there is an option to set up the space below the paragraph, maybe it can help to solve your question.
My detailed answer here shows how to use the list continuation style to insert unidentified list items into a list. This method may offer a solution. Behaviour related to copy/paste of an ordered item into an existing ordered list will likely depend on whether it is the first list item that is being copied. This item isually has a restart identifier definition.
