So Mr. Wizard points out here that we can get all the FE packets via FrontEndExecute[FrontEnd`NeedCurrentFrontEndSymbolsPacket[]][[1,1,4]]
I was wondering what all the other element are. I think I've managed to pin a number of them down: (Ignore the MyTools` context. It's just the context I give to my tools application.)
{
{
{MyTools`$FESettings, MyTools`$SeeminglyRandom,
MyTools`$FEDataForms, MyTools`$FEPacketList},
{MyTools`$FEBoxForms, MyTools`$FEInterfaceStuff}
},
MyTools`$FEData
} = FrontEndExecute@FrontEnd`NeedCurrentFrontEndSymbolsPacket[];
The thing is, the only ones of those assignments that I'm actually confident are, (obviously) the packets, the data forms, and the box forms. In particular, the <FE Call>[[1,1,2]] element is very confusing.
For those just scanning it looks like:
