Consider the situation, when you need to refer to a particular point of code in the file, modified by
some of your
colleagues, or you want your colleague to look into the same piece of code you are currently viewing.
The code
pointer is visible to your fellow developer instantly, and enables navigating to that particular piece
of code in
one click.
Tip
To view the code pointers, the
recipient of your message should have the same piece of code available. Otherwise, he or she is unable to
navigate
to the place you point to.
