You can step through the analysis technique code line-by-line to analyse it and to watch variable's values as they change. There two three different types of step commands. The differ only by the way they treat analysis technique calls:

1. Step Into - use it when you want to pass to the next line. If current line contains analysis technique callyou will be passed to this analysis technique. Press F10 to step into (alternatively, you can use Debug->Step Into from debugger main menu).
2. Step Over - step over is similar to step into, but if current line contiains analysis technique call it will be called, but you will not be passed th this analysis technique. Press F11 to step over (alternatively, you can use Debug->Step Over from debugger main menu).
