- A table of contents is helpful for quickly locating where certain content can be found in a document. For both sighted and nonsighted users, it's important that the TOC in a PDF file can jump to the desired location with the click of a mouse or the tap of a keyboard. Although ideally you'll want to do this by adding the functionality in a source document using a program such as Word or InDesign, sometimes you'll have to do it manually. Let me show you how this is done in Acrobat DC. So I'm going to start by navigating to page 2 of my document where we have the beginning of the table of contents.
And what I want to do here is open up the Tags pane and I'm just going to grab my selection tool, select some of this text, and choose Find Tag from Selection and that's going to show you the table of contents here, we have the TOC tag, and then all of the contents within there. And you can see all of our table of contents entries in here, those are tagged as TOCIs. So I basically want to be able to link these entries to the appropriate location. So what I'm going to do here is I'm going to come up here to Section 1 Introduction and using my selection tool, I'm going to select that text and then what I'm going to do is right click and choose Create Link.
And this brings up the Create Link dialogue box where we can determine the Link Appearance so we're just going to go with an Invisible Rectangle, and then we can choose the Link Action. Now when it comes to manually re-mediating this document the only we choice we have for a Link Action is really to Go to a page view. I really wish we could link to a specific destination but the best we can do is go to a particular page at a particular view. So what I'm going to do here is I'm going to choose Go to page view, and I'm going to click the Next button and we'll get a dialogue that basically tells us use the navigation tools in Acrobat to navigate to where you want to link to and then click the Set Link button.
So what I'm going to do is, using my page navigation tools up here, I'm just going to navigate to the Introduction section. So there it is, Section 1 Introduction and I'm going to click the Set Link button. So now you can see that link is going to go to that page. Let's go ahead and do another one, where it says Changes in Policy, I'm going to go ahead and select that, right click and choose Create Link, and then we're going to navigate to that particular page. So I'll go to where it says Introduction or Changes in Policy, click on Set Link, and that is going to link to the appropriate location.
Now if you look in the Tags pane, what you'll see is that the true Link tag has been created. We have the Link OBJR tag that was also added and then here's the content for the link. So I'm not going to go ahead and do all of these because that's going to be pretty time consuming but I just want you to understand that now if we go to our hand tool, and we click on one of these, for example Changes in Policy, it's going to jump to that location on the page. And although from a accessibility perspective it's not going to jump exactly to this text, it's actually going to jump to the top of the page, at least you're getting them to the appropriate page and then they can go ahead and find that section.
Although it requires a bit of work, the end result is navigable table of contents that allows a user using assistive software to jump to a specific location quickly and easily.
