To find such terms, the fastest way should be the following:
At the Search tab, run the Search. For instance, if “Advanced Data” is translated into Spanish as “Datos Avanzados”:
Source: "Advanced Data"
Target: -"Datos Avanzados"
Case Sensitive checkbox: Enabled.
PowerSearch: On (Ctrl+P)
Click the Add Last Search to Checklist… link at the right of the Search options toolbar.
Alternatively, create a glossary in tab-delimited text file format. Column A should be source and column B target.
Add source and target terms including capitalization.
Save the file and add it to your Xbench project as Key Terms.
At the QA tab, enable the Key Term Mismatch checkbox at the Content check group.
Enable the Case-sensitive Key Terms checkbox at the Options section.
