# What are all the returns from FrontEndNeedCurrentFrontEndSymbolsPacket

So Mr. Wizard points out here that we can get all the FE packets via FrontEndExecute[FrontEndNeedCurrentFrontEndSymbolsPacket[]][[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$FEData } = FrontEndExecute@FrontEndNeedCurrentFrontEndSymbolsPacket[];  The thing is, the only ones of those assignments that I'm actually confident are, (obviously) the packets, the data forms, and the box forms. In particular, the <FE Call>[[1,1,2]] element is very confusing. For those just scanning it looks like: "Graphics", "NotebookDefault", "Clip", "Infinity", "None", "Notebook", "Vertical", "Bottom", "RGBColor", "Null", "Generic", "BeforeCell", "Before", "GlobalPreferences", "Baseline", "Left", "Axis", "GrayLevel", "Placeholder", "Queued", "ToggleFalse", "Closed", "Toggle", "Full", "ForwardBackward", "Preemptive", "Tiny", "Forward", "Backward", "Open", "CellGroup", "Expression", "GeneratedCell", "Version2", "Version1", "True", "All", "AutomaticPreview", "False", "After", "AfterCell", "ButtonContents", "Top", "Manual", "AutomaticCenterLeftCenterRight", "Style", "Fixed", "AutomaticLeftCenterRight", "Empty", "Short", "Fit", "FitAll", "Automatic", "SoundAndGraphics", "AlignmentMarker", "Sound", "FullWithinScreen", "Center", "GroupTogetherNestedGrouping", "Selection", "WindowWidth", "PaperWidth", "Inherited", "GroupTogetherGrouping", "GraphicsGrouping", "Cell", "Small", "OutputGrouping", "InputGrouping", "Round", "Scaled", "CellContents", "DialogBox", "SectionGrouping", "Scrollbars", "TitleGrouping", "Previous", "Scrollable", "EvaluationCell", "Next", "ShrinkToFit", "Long", "NormalGrouping", "VisibleCell", "Ceiling", "Rotate", "ResizeToFit", "Floor", "Expand", "ButtonCell", "ButtonData", "LineWrapParts", "Medium", "Wipe", "Sizing", "TextParagraph", "Ex", "Push", "Above", "$SystemCharacterEncoding",
"TextLine",
"GlobalSession",
"GraphicsContents",
"Word",
"Locking",
"Horizontal",
"Character",
"Right",
"SelectionCellDefaultStyle",
"Large",
"Language",
"SelectionCellParentStyle",
"SelectionCell",
"RightClickTarget"


Whereas, say, the stuff I pegged as interface stuff (I guess this is all interface stuff, by I was thinking more like the notebooks/front ends/menus stuff) is:

"Notebook",
"Cell",
"CellGroup",
"CellGroupData",
"CellTags",
"CellLabel",
"FrontEndVersion",
"AutoScroll",
"CellObject",
"Interactive",
"InsertionPointObject",
"Above",
"Below",
"ParentList",
"FrontEndObject",
"NotebookObject",
"WindowTitle",
"FontReencoding",
"Interlaced",
"TransparentColor",
"SpanningCharacters",
"Box",
"Baseline",
"CellBoundingBox",
"CellElementsBoundingBox",
"ContentsBoundingBox",
"ShrinkWrapBoundingBox",
"GeneratedCell",
"Selection",
"IgnoreCase",
"NotebookSelection",
"AnimationDirection",
"Forward",
"Backward",
"ForwardBackward",
"CellStyle",
"Open",
"Closed",
"EvaluationCell",
"RawData",
"StyleDefinitions",
"$FrontEnd", "$FrontEndSession",
"\$DefaultFrontEnd",
"Hue",
"CMYKColor",
"Item",
