Highlighting and annotating chemical terms in an online journal article. Screenshots showing the effect of the ChemGM.user.js userscript on the Chemistry Central Journal web page (full URL: [47]) for Majumder et al. [48]. (a) When the userscript is running a toolbar is added to the top of every webpage. Clicking the highlight button in the toolbar causes the contents of the webpage to be analysed for chemical terms. (b) shows the original text of the abstract. (c) After a minute or so, any chemical terms recognised are highlighted in yellow, and are annotated with hypertext links to their entries in PubChem (if available) and a 2D depiction of the image.
