Hi Richard. The Pikchr-based syntax diagrams now allow selecting text in boxes. But could they be links, to jump to the appropriate details for that expression/keyword/etc...? Would avoid having separate textual links after each diagram, thus less clutter on these pages, and easier navigation too. Of course, this may affect accessibility. But screen-readers are aware of links, aren't they? And before the images were completely opaque to them anyway, so accessibility is likely improved now I suppose. Just thinking aloud. Not sure whether links in Pikchr were discussed before. *Edit by drh: correct spelling of "Pikchr"*
