Here is how to make a search list directly. The moment you start putting files on the search list, Nisus switches its search scope to Search Search List . In the Catalog window you can see the contents of only one folder at a time, but there is no law saying that files in the search list cannot come from different folders. Unfortunately, this means that it can be rather difficult to check the search list to see what's on it, since, other than looking through various folders by way of the Catalog window, Nisus provides no direct way of examining the current search list. Running this macro puts the current search list onto the current clipboard, where you can look at it.
Files stay on the search list until they are removed.
One way to remove a file from the search list is to do so explicitly, with Remove From Search List or Clear Search List . Obviously this is rather frustrating if you need to search the same set of files again for something else. Fortunately, Nisus comes with macros called Save Search List and Restore Search List which allow you to retain a search list across searches. If you think you're going to want to perform more than one search on the same set of files, you should create the search list in the Catalog window, then run Save Search List , then perform the search, and then you can run Restore Search List and run a different search on the same files. Naturally, we'll write one.
