If i understand well what you want to do e.g Adding properties to the first line that don't start with "#" and is not an empty line, the simple code above suffice. ,---- | X ==> point | | # One line starting with #. | | the line we want to add text properties to. `---- If you start to X (point) just running M-x test-prop will highlight the line you want. Is it what you want to do? -- A + Thierry Volpiatto Location: Saint-Cyr-Sur-Mer - France
