No idea, it is an entry in the Accel.cfg.
I checked it for You, it is in section.
# Ctrl+Right-click links to to the background
Why I did not bother to check it the first time?
Once You knew the second part = ID_OPEN_LINK_IN_BACKGROUNDTAB of this You were able to redefine the accel for Your own liking via
Edit > Configuration > Accelerators
This gets to Your personal accel file which overrules the default file which must not be changed (= in ./defaults/settings/accel.cfg. And can be used to look up info locally).
