I have not tested this feature

but i had the meaning it works like this:

* execute an Find in Files command for an “word”

* you get an result like:
C:File1.txt Line 3 in this line is the word
C:FileB.log Line 25 here is this word too

* select an line and use “Edit > Advanced > Tag Jump”
this command will open the file and jump to the line number in question.

Maybe you can try it yourself?
