Rick wrote earlier about how you can go from a headword in one lexicon to another by right-clicking and executing a keylink from the headword. This is true, and a very useful feature.
But I will show you a still more excellent way …
Once you have a lexicon open to the article you want to read, the quickest way to survey other lexicons and dictionaries in your library is to use the Parallel Resource feature. Whenever you have a resource open, the Libronix DLS does a lot of work behind the scenes to cull through your library to find resources that work in roughly the same way as the one you have open.
The Go | Parallel Resources menu will show you what all these resources are, if you want to choose one randomly from the list. Or you can use the Go | Next/Previous | Resource menu options, which are duplicated on the resource window’s toolbar (big yellow arrows pointing up and down). Usually those arrows advance forward or backward in the current book, but if you hit the little black downward-pointing triangle next to each button, you’ll see a menu of options, one of which is Resource.
