Links are most often automatically identified by Equidox when a document is imported. You can check to be sure Equidox has done this correctly in the HTML by pressing the Preview button. Active links will show as such and will convey the user to the correct webpage or open an email window when clicked.
Should the link be inactive in your Preview, copy the link address from the Preview page to your clipboard and go back to the Page Detail. Create or select a zone around the Link (Arrow 1). Be sure the zone fully encompasses the entire text of the Link. Then go to the Type drop-down box under Zone Properties in the Zone tab and choose Link (Arrow 3). Paste the copied URL from your clipboard into the URL/Anchor field (Arrow 4) under Link Properties. Then Preview the page again to be sure the Link is now active. You can set the Link Name (Arrow 2), add a Description (Arrow 5) and Merge the Link with text on a previous page or column (Arrow 6).
