You can get WordSmith to compute some results simply by dragging.
If you have WordList open you can simply drag a text file onto it from Windows Explorer and it will create a word-list there and then using default settings.
If you have KeyWords open you can simply drag a text file onto it from Windows Explorer. If you have a valid word list set as the reference corpus, it will compute the key words.
If you drag a word-list made by WordList (.LST ending), a concordance (.CNC), a key word list (.KWS) etc. onto the Controller, it will open it with the appropriate tool.
