Searching in the Installed App
With the TextExpander window open, look in the upper left corner for the “Search” field. A search will filter the Snippets in the TextExpander window based on the search term. TextExpander will search your Snippet content, abbreviation and label.
Any Snippet Group containing a matching result will appear in the Groups list. You can adjust how your search results are sorted and presented by going to the View menu or right-clicking a Snippet in the search result.
Clear the search field to see all your Snippets in the TextExpander window again.
