Unduplicate is a small tray utility for removing duplicate lines of text from data held in the clipboard. When run, it will first display a small window that will allow you to have control over a few options affecting program operation.
When the options are set to your liking, you can hide the small window leaving the icon in the system tray, by selecting the "Continue" button. The "Close" button shuts the program down.
Your data may or may not contain a heading in its first line. The top three options are radio buttons that let you either protect the heading from being sorted (and possibly removed), force the heading to be removed, or say there is no heading.
It may be important that the original order of the data is preserved, apart from removal of duplicates (the first occurrence of a set of duplicates is always kept, 2nd, 3rd occurrences etc are deleted). The checkbox labelled "Maintain original order" is used for this purpose (defaulted to YES).
When you click on the tray icon with the LEFT mouse button, duplicate lines are removed from the clipboard in accordance with the option chosen.
If you click with the RIGHT mouse button, the small window is shown again,
in case you want to modify the options or close down.
