AntConc - Concordances and wildcards

A screencast explaining how to use wild cards in AntConc's concordance analysis.
Notes
Software used: AntConc3.2.1 -- website: www.antlab.sci....
At the start of the video I mention that I assume that a word list has already been generated. Just to clarify: you do not have to generate a word list before generating a concordance.
You can also change the wild card character to anything you like -- in AntConc's Global settings: Wildcard settings
Acknowledgments
My thanks go to Bethany Stanford who collected the corpus used in this video (15 speeches given by Barack Obama over the course of his election campaign which ran from 2007 to his subsequent election and inauguration in 2009). My thanks also go to Laurence Anthony for useful feedback on this video which I have incorporated in the notes above.
