The "Find in Expressions" menu option is located with the Group Bar at the Database Explorer when "Labels" is selected. The key combination [Ctrl]+[Shift]+[F] is also available to launch the "Find in Label Expressions" dialog from the Database Explorer. The search criteria can be modified based on case sensitivity and whole words.
The entry box is also a drop down, where the search history is available. To clear the history, press the [Ctrl+R] key combination. The search history is saved in the C:\Users\<User>\RBTI\ folder within the RPTVAR.RST file.
After the search is complete, a list of labels and defined variable expressions that match the search will be displayed. The Date/Time and Version is available to see when the object was last altered. The search results will contain the tables(s) and expressions that match the search criteria. The variable expression can be launched within a dialog window for editing by double clicking on it, or by selecting the "Edit..." button. Upon making changes, the "Save" button may be used to save the label. The "Expand All" check box allows the list of expressions in the search results to expand for full viewing. The search results can be saved to several output formats.
