I don't think you can do it with just one macro if you don't want to give the whole paragraph text as a macro argument. (How is the code to know when the indent should be over?) But, as you suggested, you can implicitly reset the indent when a "normal" paragraph is started. I don't think mm has a hook for this, but you can "wrap" mm's paragraph macro with additional code: .\" mm .\" ---------------------------------------------------------------- .nr tI 0 .\" ---------------------------------------------------------------- .\" tagged paragraph .de tP .oP .nr tI \w'\\$1\ \ 'u .in +\\n(tIu .ti -\\n(tIu \&\\$1\ \ \c .. .\" ---------------------------------------------------------------- .\" end tagged paragraph & restore indent .de eP .if \\n(tI 'in -\\n(tIu .nr tI 0 .. .\" ---------------------------------------------------------------- .\" redefine mm's paragraph .rn P oP .de P .eP .oP \\$@ .. .\" ---------------------------------------------------------------- .ll 5.6c .H 1 "A Test" .P I often need to typeset single hanging paragraphs like: .tP PS: Example of a post-scriptum, it has a hanging indent. .P I have created a macro for this.
