There are two basic ways to find information in Chinese Toolbox. One is through the Search window; the other is through context menus of main entry frames in dictionary windows.
Context menu search:
To find information about an entry, right-click one of the dictionary main entry frames to show menu options. See Tip #10 (for characters) and Tip #11 (for words).
These two methods can be combined: e.g. (1) Search for an entry via a dictionary context menu. (2) In the Search window specify 'Previous results' as the scope of the next search.
