How are they called? What packages do they belong to? It is useful for configuring them via dconf, reporting bugs and so on but hard to find out. I remember there was similar question for 11:04 but cannot find it.
These are the indicators on my system:
There are ten, the last one on the left is Tomboy, the rest is more or less default (the second from the left is displayed only if more than one keybord layout is used). What are their names? And the names of their packages?
