Finding out where a function is called

You may be interested in knowing where any functions among the list of matches are called. You can do so using predefined regular expressions filters in the Find and Replace Filters dialog.
As an example, let's see where function

mousepress is called. To do so:

In the Retriever, highlight the first match in the list of matches. It should be

831: mousepress (f,n)
Press the Filter... button.
The Find and Replace Filters dialog appears.
From the list of regular expression filters, select call and press Ok.
Now the list of matches only displays those matches in which function mousepress is called. You should notice that there are 5 matches in 4 files.
