Low-Level Recording?enables you to record on any object in 
your application, whether or not QuickTest recognizes the 
specific object or the specific operation. This mode 
records at the object level and records all run-time 
objects as Window or WinObject test objects. Use low-level 
recording for recording in an environment or on an object 
not recognized by QuickTest. You can also use low-level 
recording if the exact coordinates of the object are 
important for your test or component.
