The textbox <Filter Tags> directly below the title bar is provided for a quick reference of tags. This option allows you to filter the entire catalog contents quickly by certain word combinations. This filter passes all Tag-Headings in the catalog Tags panel and immediately displays all text matches in a list form.
As soon as you enter a combination of letters, a list of all the tag entries containing this combination will appear here.
In each case, the matching with the input word elements are shown in red. In this way you can search for one tag, which exact spelling is not known or you can use it for example to quickly find out whether a particular tag was already used and thus already exists or whether it is possibly duplicated.
