If I have an object, such as a circle or rectangle, with a label (text inside), how can I make turn a word of that text into link, a hypertext web link with a backing URL?
For example, within the OmniGraffle app or an exported PDF, in the object shown below I want to be able to click on the word JDK and have my web browser open to https://en.wikipedia.org/wiki/Java_Development_Kit.
Linking to a box or other drawing object is the easy thing to do. It's not a true link to text like you asked, but maybe a small object surrounding the text would be worth the hassle.
Now on to the easy option:
* Open the action triangle (if needed) and select @ Open a URL and paste in the link you wish to have linked
