Here's how it works:
1. Select the word you want to find a synonym for.
2. Right-click on the selected word.
3. Look for a "Synonyms" or "Thesaurus" option in the context menu that appears.
4. Click on it, and a list of synonyms will usually appear.
Note: This feature might be called different things depending on the specific word processor you're using (e.g., Microsoft Word, Google Docs, etc.).
