Just drag the link text tag (“Hyphenation”) and drop it underneath (as child of) the tag, at the same level as the Link-OBJR tag. Such links work with a mouse and appear normally in the tab order but don’t work with screen readers. The tag in question – in this case containing the word “Hyphenation” – will be created at the same level as the tag, rather than being a child of it. The problem is that the tag containing the link text will be created at the wrong level in the tag tree hierarchy. InDesign originated links Figure 2Īs of the date of writing, hyperlinks created in InDesign (CS4), when converted to PDF, will produce inaccessible tag structures. However, links currently authored in InDesign will need fixing, as will those found in untagged PDFs. Provided that PDFs are tagged on creation, links originated in Microsoft Word documents will have the required tag structure and will present no problems (provided that they don’t span two or more lines). The Link–OBJR tag enables assistive technologies to properly recognise the link and handle it correctly.Ī complete, accessible link tag structure can be seen in Figure 1 above. a Link–OBJR tag which must also be a child of the tag.one or more child tag(s) containing the link text.Figure 1įor a link to be accessible it must have a specific tag structure consisting of: TaggingĬreating links that are accessible is a single A requirement under the Web Content Accessibility Guidelines (WCAG) 2.0., and is vital in ensuring the accessibility of PDFs.
