3.4 Using Writer2LaTeX and Writer2BibTeX as export filters
If you choose File – Export in Writer you should be able to choose LaTeX 2e, BibTeX data file as file type.
Note: You have to use the export menu because there is no import filter for LaTeX/BibTeX. You should always save in the native format of OOo as well!
Note: Currently embedded graphics are not converted when Writer2LaTeX is used as an export filter. Also using Writer2BibTeX in conjunction with Writer2LaTeX is currently only possible from the command line. This is because of an issue with xmerge. A fix for this is planned for Writer2LaTeX version 0.3.4.
