This appears in the summary of the debugger tutorial chapter. The 
chapter itself is a guided tutorial on using the debugger on a sample 
program, and includes using the Filt

The debugging chapter in the tutorial (which shows the screencap you are 
pointing to) has an example of using the filter with a Goal Template and 
condition, along with using spy-points. It is intended for people who 
are unfamiliar with debugging in Prolog, and also introduces some of the 
more advanced features such as the Filter, and we would welcome any 
feedback to improve the chapter.

The chapter was written some years ago before we added break-points to 
ECLiPSe, and has not been updated for break-points, partly because I did 
not see a quick way of introducing it with the simple example used. 
Looking at it now, there also seem to be a typo in the example Filter 
condition (figure 5.4): the condition should be (X == 4 ; Y == 4).
