Hello, I try your hints, and this is the outcome: A) your hints about deleting the date works perfectly.
B) your hints about {} works: also on my keyboard AltGr+7 and AltGr+0 . before I tried to use Alt+123 and Alt+125, but such command did not work with LyX. C) Bibliography I used the information on www.lyx.org/help/... it works. In detail, in the preamble: \renewcommand{\@cite}[2]{{#1\if@tempswa , #2\fi}} \renewcommand{\@biblabel}[1]{} D)footnote: I used the information on www.lyx.org/help/... it works: \renewcommand\@makefhmark{\relax}. However, I have to put the note not in the author environment, but at the beginning of the standard environment. But I guess it really does not matter, because no label is visible. Other questions: 1) I would use the spellcheker for my English documents, but also for the Italian ones, if it is possible. But the edit->spellchecker command does not works. A Warning is shown to me. Something similar to:" Perhaps you do not have a dictionary file for the language of this document installed. Check /usr/lib/ispell (I use GNU/Linux Mandrake 8.1, kernel 2.4.?)" In such a directory I find only to files "italiano.aff" and "italiano.hash" and some links to them. What can I do? Where can I find/download the required files (if the problem is really this)? 2) I have then to export my document in LateX format on a "PC IBM formatted " floppy. Is it absolutely sure and safe this export operation from Lyx to LateX, as I suppose, or may I have some conversion problem between the two format Lyx and LateX? In fact I must submit only latex document. A curiosity: but then the people to whom it is addressed what kind of tool will probably use to read it? Can they read such exported file both in windows and in GNU/Linux or other S.O. Unix-like? Carlo
