In subject windows, the commands locate and select the next article whose author name or subject contains the search string. If the next matching article is inside a collapsed thread and the match is in the author name, the thread is automatically expanded. In article, message, and text windows, the commands locate and select the next occurrence of the search string in the text. Digests usually begin with a table of contents. If you see something interesting in the table of contents, select it, then use Enter Selection and Find Again to quickly jump to the interesting article.
All searches are case and diacritical insensitive substring searches.
In the Subject Window, and the Full Groups List, you can use live filtering to show only a subset of items in the list that match a search term that you type in. The contents of the window update as you type. To show everything again, simply delete the search term so that everything is matched. For live filtering to work in the Full Groups List, you also have to be viewing the groups as a flat list, so the Hierarchical list checkbox must be off. Now simply type into the text field.
