Dear Silvain, thank You, this worked perfectly for me! Providing you have juste one space as in the example, in the part \mark \markup { you can do a search and replace
\\mark.\\markup.{[^{]+{[^}]+}[^}]+} with nothing (I tested it in Geany on Ubuntu) dot means one character [^{]* means a non-empty sequence of characters without any { character \ needs escaping Your could add \s at the end to remove empty spaces or lines Le 25.05.24 à 18:15, Stefan Thomas a écrit : Dear community, I would like to remove automatically all the "\mark \markup { \box { LETTER } }" in the below quoted text.
