Okey guys After the message about Nedit, now I have the programme runing fine because: 1) Having the "Lock Num" key dissabled, the shortcuts keys run fine. 2) If I like differents colors that the default ones (white background, black text) just I need to start the programme with options, for example: nedit -background black -foreground white 3) From the xtexsh I can start nedit with all this commands changes ^_^ Have a nice day _____________________ Francisco Alcaraz Ariza Department of Plant Biology Faculty of Biology University of Murcia Murcia (Spain) work e-mail: [EMAIL PROTECTED] home e-mail: [EMAIL PROTECTED]
