Forums mIRC Help Ctrl + l - what does the red line mean?

When you press ctrl +l in mIRC there appears a red line in the channel / query.
What does this "thin red line" mean. Why is it there - what does it really do?

From the help file:

Line marker
Whenever you close or minimize a window, the line marker marks the spot where new messages come in to a channel or query window. This allows you to scroll back and easily see which messages you've missed.

You can press Control+L to scroll back to view the line marker. The line marker is only updated after you've scrolled back to view it.
