I can be completely wrong about this, but as I understand it, this is how e-Sword works...
e-Sword is constantly "looking" at the word under the mouse pointer (i.e. a mouse over event).
When it sees a word that matches a particular format, say one that starts with the single letter "H" or "G" and is followed by a series of numbers....."G2384", that mouse-over event is triggered and e-Sword will then look in the dictionary that was set-up in Options as the ToolTip Lexicon. *IF* that word is found in that dictionary (Strong's by default), then a tool-tip pop-up occurs displaying the dictionary entry.
For those of us creating modules, Strong's number style text (H999 & G999) is the only available "trigger" for for pop-ups in e-Sword.
Now for another "built-in" feature of e-Sword. If you click on "ANY" word in e-Sword, "AND" that word is in any of your active dictionaries, a indicator displays on the dictionaries tab. In my example I had the short little dictionary I threw together active and open below the commentary window. I made entries in the dictionary, making the "Word" the Morph text, i.e. "N-AM-P". So, when I click on that word "N-AM-P", I am just using a Built-in function of e-Sword. I did not have to "tag" anything.
Some people have made dictionaries utilizing "Strong's" numbers as the word entry in that dictionary, but changed the definition's text to display what they want.
Others have done something similar. They "extend" the Strong's number set. They keep the original numbers intact, but add additional numbers past the original ending range.
For Hebrew - H8675 & forward. For Greek G5625 and forward. Now this does work, and you can keep the function of regular Strong's numbers, but.....
Neither of these is a good idea in my opinion. Why? This can lead to confusion for the user...
You have to set this dictionary as the default tool-tip dictionary and if you simply re-purposed the regular Strong's numbers, this can break the "regular" function of Strong's numbers.
Then, you hover over one of these "New" links, expecting a Strong's definition, but get a TVM explanation instead. Whats up!?!?!
More later.....
