After different attempts at it, I realized that the following works perfectly for deselecting the currently active bold tag. It still suffers from the problem that when I 'switch on' the tag it adds a space - but I can live with it... thanks! alessandro -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ / Dr.Alessandro Magni \ Electromagnetics Division / INRiM Strada delle Cacce 91, 10135 Torino (ITALIA) \ Email [email protected] / Tel: 0039-011-3919821 Fax: 0039-011-3919834 \ URL http://www.inrim.it/~magni / Our business in life is not to succeed but to continue to fail \ in high spirits. -- Robert Louis Stevenson ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
