Add stack, queue and simple text transformations to the Windows clipboard when using the clipboard's keyboard shortcuts. As well as storing successive clipboard items in either a queue or a stack nbClipboard can perform search/replace operations on the clipboard data and can automatically convert the text to either upper or lower case. This tool can be left running in the background or you can make the window stay on top or become transparent. It is necessary to have the .NET framework version 3.0 installed for nbClipboard to work. Version 3.0 of the framework is pre-installed on Windows Vista and can be downloaded from Microsoft's website as an additional download for Windows XP.
