When debugging an application it can be very helpful to have a way to invoke the TRACE command ad hoc from the keybaord. Stepping through numerous breaks at a TRACE command can be maddening. Add the method below at any place in your code that you would like to add the TRACE command. This example method is called DTrace.

This method is most helpful when a developer is observing the execution of an application and trying to debug a method or series of methods after certain conditions have been observed or are anticipated to exist. By using DTrace instead of TRACE, a developer can let the code of interest run uninterupted until the key combination is pressed. This way the TRACE command will only be invoked when it is really necessary.
