In Libronix you have the option to double click any English word in any Resource Window and the Merriam-Webster’s Collegiate Dictionary (Eleventh Edition) would open. How can I get L4 to do the same?
If you double-click a word in L4 it will open the highest-prioritised resource indexed by English headword which contains the word you have clicked.
So to achieve this you need to prioritise Merriam-Webster above other dictionaries in your library.
Information about how to prioritise resources is available at http://wiki.logos.com/Prioritizing
This means that you could choose other of your dictionaries if you would prefer.
Hope this helps
