Attribute match types are explained in Chapter 12 of the foundation training course, maybe revisit that? Basically it allows you to not require exact text comparisons when evaluating an element attribute. So if the window title of your application is something like ""Customer Details - 12345"", where 12345 is the account number, your Application Modeller element might set match time for the window text attribute to be wildcard and you can change the match text to be ""Customer Details - *""
