The Sidebar can be opened and closed by clicking on the Sidebar button in the toolbar. The Sidebar is split into two sections.
When Babylon-Pro displays results, the top-most section of the Sidebar displays the list of glossaries that currently show results. Clicking on the name of the glossary in the Sidebar will scroll the results to show the definition from that glossary.
The bottom section shows links to common operations:
Glossary options - Will open the glossary options dialog.
Configuration - Will open the configuration dialog.
Web Search - Will perform a Web Search on the current term.
Conversions - Will open the conversions utility.
