Thanks for the feedback. As to the question, what is scatter-gather? -- It's the idea of gathering up scattered pieces of text and consolidating them in another place, whether elsewhere in the same buffer or in another file.
Using tags would work, and I've done something similar in my home-brew code for a fiction writing environment (I gather scattered comment blocks). So would non-visible marks, although when brainstorming you may want visible indicators of selected headlines. Something like '** ! headine' doesn't really destroy org syntax in any way, but it does add extra text to a headline (of course, so does a tag). I'll certainly look at the suggested alternatives, especially helm. In any case I'll think this through quite a bit more before developing a prototype. -- Bob Newell Honolulu, Hawai`i * Via Gnus/BBDB/Org/Emacs/Linux *
