  2. Adjust your KAST expression and test case as needed and re-test. Checker Studio automatically responds to your changes by searching the source code and AST. (Make sure that Image:KAST_tutorial1_auto_button.png Automatic Pattern Application is on.)

    You can look in the context-sensitive help for functions that are applicable to the currently highlighted expression.
