[gst-devel] Where can I read about signals?

[wl2776]

I read in the playbin2 documentation:

Signals 
 "about-to-finish"                                : Run Last
...
 "get-audio-tags"                                : Run Last / Action
...

What does it mean?
Google shows, there also Run First can exist, however, it didn't bring me
any links to the documenation.
