Org-modes radio targets are useful for automatically adding definitions to terms used in a text. You can define a term within triple angled brackets, like in this definition line:
<<<my term>>> my definition of 'my term'
and all occurrences of the term "my term" in the text will be converted to hyperlinks that links to their definition line. For instance if the term was"Emacs", the definition line could look like this:
<<<Emacs>>> a useful text editor
But clicking such radio targeted links in a text will move you to its definition line, somewhere else in the text. After reading the definition you have to orient yourself back to the place in the text where you clicked the link, to continue your reading. This is impractical. I have two questions:
1) is there a back jump function that let m find back to the clicked link?
2) is it possible to make emacs show the definition of the linked term, as a pop-up window, when hovering the mouse over the link?
