CurrentValue can be used to poll the state of numerous system values such as the mouse position. Its help page doesn't list all possible items, though. An item like "TooltipFontFamily" isn't listed but it works nevertheless:

In[49]:= CurrentValue["TooltipFontFamily"] Out[49]= "Segoe UI"

My question is: where can I find a (more) complete list of items that can be used with CurrentValue. Or, alternatively, how could I programmatically generate such a list?

EDIT

Based on John Fultz' answer I wrote the following:

Union[ Flatten[ Cases[ Import[#], HoldPattern[CurrentValue[a_]] :> a, Infinity ] & /@ FileNames[#] & /@ { FileNameJoin[{$InstallationDirectory, "SystemFiles", "FrontEnd", "StyleSheets", "*.nb"}], FileNameJoin[{$InstallationDirectory, "SystemFiles", "FrontEnd", "TextResources", "*.nb"}], FileNameJoin[{$InstallationDirectory, "SystemFiles", "FrontEnd", "SystemResources", "*.nb"}] }, 2 ] ]

and got this:

(* ==> {CommandKey, ControlKey, ControlsFontFamily, ControlsFontSize, DefaultButtonSize, DefaultNewGraphics, HyperlinkModifierKey, LicenseValid, MenuFontFamily, MouseButtonTest, MouseClickCount, MouseOver, NotebookSelected, OptionKey, PanelBackground, PanelFontFamily, PanelFontSize, ScreenArea, ShiftKey, ToolbarBackground, TooltipFontFamily, TooltipFontSize, TooltipFrameMargins, Enabled, Language, {ControlsFontSize, Large}, {ControlsFontSize, Medium}, {ControlsFontSize, Small}, {SystemColor, DialogText}, {SystemColor,DialogTextDisabled}, {SystemColor, MenuText}, {SystemColor, Tooltip}, {SystemColor, TooltipFrame}, {SystemColor, TooltipText}, {TaggingRules, Highlight}, {ScreenRectangle, 1, 2}, {ScreenRectangle, 2, 2}} *)

in addition to a message complaining about:

Syntax::sntufn: Unknown unicode longname NumberComma.

Other items known by CurrentValue (not in the list above) that were used in answers/comments here:

  • As per this comment by celtschk:

    {"Thickness", "Opacity", "Dashing", "FontFamily", "FontSize", "FontSlant", "FontWeight", "FontColor", "FontOpacity"}

Other answers have already suggested ways of querying options. There's no way of systematically generating a list of all string values, but it's not too difficult to put together a list of all of the values which are used by Wolfram Research in Mathematica itself. If you look in the various files in these locations:

  • $InstallationDirectory/SystemFiles/FrontEnd/StyleSheets
  • $InstallationDirectory/SystemFiles/FrontEnd/TextResources
  • $InstallationDirectory/SystemFiles/FrontEnd/SystemResources

for instances of CurrentValue, you'll get a pretty good list of what is in active use by Wolfram Research developers at any given time. Most of the undocumented string values are created specifically to fulfill a purpose required by one of these files, so that's a pretty good list.

There may be a few others used directly by the kernel but not anywhere in these files, but if so, not many. Any undocumented string values which are not in use by the product somewhere are likely to be untested as well, so if you're tempted to complain that this list isn't absolutely complete, be careful what you wish for.

These String items were directly read from the 10.0.2 Front End, including quite a few not listed elsewhere in this Q&A:

To my understanding CurrentValue adds an alternative syntax to what Options and SetOptions provide for the frontend and notebooks. So in addition to what's documented I think Options[$FrontEnd] and Options[Notebook] would be a good starting point. These are what I usually consult when searching for something.

  • $\begingroup$ That certainly yields a lot of options but the example I gave ("TooltipFontFamily") is not among them. That suggests there must be more options to be found than only those. In those list most of the options are not strings BTW, whereas most of the values listed in the CurrentValue doc page are strings. $\endgroup$ Commented Feb 5, 2012 at 23:36

    $\begingroup$ @SjoerdC.deVries: you are absolutely right about the fact that my list is not complete, and I know that very well. You should keep in mind that many options can nowadays be given as strings or as a symbol, try e.g. CurrentValue[AutoIndent] vs. CurrentValue["AutoIndent"]. Something that is also not clear to me is why there is a TooltipBoxOptions -> {"DefaultLabelStyle" -> "TooltipLabel"} and CurrentValue["TooltipFontFamily"] and if and how they are connected. Looks like a rich field for experiments... $\endgroup$ Commented Feb 5, 2012 at 23:47

Basing on Sjoerds self answer, you were missing the subdirectories. I added that and the tr files (don't know if it was worth something). Probably I'm missing some others because this doesn't check box structures, but it does get a few extras

fnames = FileNames[ "*.nb" | "*.tr", {FileNameJoin[{$InstallationDirectory, "SystemFiles", "FrontEnd", "StyleSheets"}], FileNameJoin[{$InstallationDirectory, "SystemFiles", "FrontEnd", "TextResources"}], FileNameJoin[{$InstallationDirectory, "SystemFiles", "FrontEnd", "SystemResources"}]}, Infinity]; fimps = Import[#, "Text"] & /@ fnames; DeleteDuplicates@ Flatten@StringCases[fimps, Shortest[ "CurrentValue[" ~~ (i___ /; SameQ @@ (StringCount[i, #] & /@ {"[", "]"})) ~~ "]"]] // StringReplace[#, Whitespace -> ""] & // MakeExpression[#, StandardForm][[1, 1]] & /@ # & // DeleteDuplicates//Sort

You get

Another way to get more stuff is to just see what's available to FrontEnd`Value[FrontEnd`CurrentValue[__]] as that's how CurrentValue seems to work its magic (per the DownValues). Then we'll use the vast output from FrontEndExecute[FrontEnd`NeedCurrentFrontEndSymbolsPacket[]] and see what sticks:

Select[ Flatten@ FrontEndExecute[FrontEnd`NeedCurrentFrontEndSymbolsPacket[]][[1]], Not@ MatchQ[ FrontEndExecute@ FrontEnd`Value[FrontEnd`CurrentValue[#], False], _FrontEnd`CurrentValue ] & ]

And we get this:

Since many people seem to be looking through files in text editors I thought I'd give a way to scrape this data automatically (it should work for any kind of expression you want, as long as it's in a .m or .nb file):

I've used this for a bunch of stuff now. First, a function to get all files of a certain spec in the installation directory:

InternalFiles[namePattern_, directoryExtensions___,depth:_Integer|\[Infinity]:\[Infinity]]:= FileNames[namePattern, FileNameJoin@{ $InstallationDirectory, directoryExtensions }, depth];

Then scrape expressions from this:

expressionsSearch[files_, pat_] := Table[ f -> Quiet@ Cases[ Switch[FileExtension@f, "m" | "wl", Import[f, "HeldExpressions"], _, Import[f] ], pat, \[Infinity] ], {f, Replace[files, Except@_List :> InternalFiles[files] ]} ] // DeleteDuplicates;

I used this on CurrentValue as such:

curValsExprs = expressionsSearch["*.m" | "*.nb", c : (_CurrentValue) :> Hold[c]];

Which gave me a massive list of returns, which I normalized some.

Here's the list of single argument CurrentValue calls:

Hold[CurrentValue["AllowDownloads"]], Hold[CurrentValue["AltKey"]], Hold[CurrentValue["CommandKey"]], Hold[CurrentValue["ControlKey"]], Hold[CurrentValue["ControlsFontFamily"]], Hold[CurrentValue["ControlsFontSize"]], Hold[CurrentValue["CurrentFormatTime"]], Hold[CurrentValue["CurrentLocatorPaneThumb"]], Hold[CurrentValue["DefaultButtonSize"]], Hold[CurrentValue["DefaultNewGraphics"]], Hold[CurrentValue["DynamicEvaluation"]], Hold[CurrentValue["Evaluator"]], Hold[CurrentValue["FontCapHeight"]], Hold[CurrentValue["FontMWidth"]], Hold[CurrentValue["HyperlinkModifierKey"]], Hold[CurrentValue["InternetConnectionAvailable"]], Hold[CurrentValue["LicenseValid"]], Hold[CurrentValue["LocalFileSystemAccessAllowed"]], Hold[CurrentValue["Magnification"]], Hold[CurrentValue["MenuFontFamily"]], Hold[CurrentValue["MenuFontSize"]], Hold[CurrentValue["ModifierKeys"]], Hold[CurrentValue["MouseButtons"]], Hold[CurrentValue["MouseButtonTest"]], Hold[CurrentValue["MouseClickCount"]], Hold[CurrentValue["MouseOver"]], Hold[CurrentValue["NotebookSelected"]], Hold[CurrentValue["OptionKey"]], Hold[CurrentValue["PanelBackground"]], Hold[CurrentValue["PanelFontFamily"]], Hold[CurrentValue["PanelFontSize"]], Hold[CurrentValue["PluginEnabled"]], Hold[CurrentValue["PreviousFormatTime"]], Hold[CurrentValue["RunningEvaluator"]], Hold[CurrentValue["SelectionData"]], Hold[CurrentValue["SelectionOver"]], Hold[CurrentValue["ShiftKey"]], Hold[CurrentValue["SynchronizationType"]], Hold[CurrentValue["SynchronousEvaluation"]], Hold[CurrentValue["ToolbarBackground"]], Hold[CurrentValue["TooltipFontFamily"]], Hold[CurrentValue["TooltipFontSize"]], Hold[CurrentValue["TooltipFrameMargins"]], Hold[CurrentValue["UserInteractionEnabled"]], Hold[CurrentValue["WindowSize"]], Hold[CurrentValue["WolframCloudActivityQueueStatus"]], Hold[CurrentValue["WolframCloudConnected"]], Hold[CurrentValue["WolframCloudLoginError"]], Hold[CurrentValue["WolframCloudUILogin"]], Hold[CurrentValue[Enabled]], Hold[CurrentValue[Evaluatable]], Hold[CurrentValue[FontColor]], Hold[CurrentValue[Language]]

Here are the ones that come as a list of arguments:

Hold[CurrentValue[{"ControllerData",{"Gamepad","Joystick","Multi-Axis Controller"}}]], Hold[CurrentValue[{"ControlsFontSize",Large}]], Hold[CurrentValue[{"ControlsFontSize",Medium}]], Hold[CurrentValue[{"ControlsFontSize",Small}]], Hold[CurrentValue[{"SystemColor","DialogText"}]], Hold[CurrentValue[{"SystemColor","DialogTextDisabled"}]], Hold[CurrentValue[{"SystemColor","Menu"}]], Hold[CurrentValue[{"SystemColor","MenuText"}]], Hold[CurrentValue[{"SystemColor","Tooltip"}]], Hold[CurrentValue[{"SystemColor","TooltipFrame"}]], Hold[CurrentValue[{"SystemColor","TooltipText"}]], Hold[CurrentValue[{GraphicsBoxOptions,AxesStyle}]], Hold[CurrentValue[{GraphicsBoxOptions,LabelStyle}]], Hold[CurrentValue[{GraphicsBoxOptions,TicksStyle}]], Hold[CurrentValue[{StyleDefinitions,"EntityFrame"}]], Hold[CurrentValue[{StyleDefinitions,"EntityFrameless"}]], Hold[CurrentValue[{StyleDefinitions,"GeneralizedEntityToggleLabeled"}]], Hold[CurrentValue[{StyleHints,"CodeFont"}]], Hold[CurrentValue[{TaggingRules,"ModificationHighlight"}]], Hold[CurrentValue[{"MousePosition","Graphics",{0,0}}]], Hold[CurrentValue[{ScreenRectangle,1,2}]], Hold[CurrentValue[{ScreenRectangle,2,2}]], Hold[CurrentValue[{TaggingRules,"values","subvalues"}]]

Here are those that occur with an object (I put in FEObject which stands for $FrontEnd, $FrontEndSession, NotebookObject, CellObject, or `BoxObject) plus a single argument that isn't found in the single argument list:

Hold[CurrentValue[FEObject,"3DPrintPreviewerApplication"]], Hold[CurrentValue[FEObject,"AddOnHelpPath"]], Hold[CurrentValue[FEObject,"AlignmentGuidesEnabled"]], Hold[CurrentValue[FEObject,"AllowDataUpdates"]], Hold[CurrentValue[FEObject,"AllowDocumentationUpdates"]], Hold[CurrentValue[FEObject,"AllowExternalChannelFunctions"]], Hold[CurrentValue[FEObject,"AutoQuoteCharacters"]], Hold[CurrentValue[FEObject,"CaseSensitiveCommandCompletion"]], Hold[CurrentValue[FEObject,"CellChangeTimeMergeInterval"]], Hold[CurrentValue[FEObject,"CodeContext"]], Hold[CurrentValue[FEObject,"Current2DTool"]], Hold[CurrentValue[FEObject,"DialogCanClose"]], Hold[CurrentValue[FEObject,"DisplayImagePixels"]], Hold[CurrentValue[FEObject,"FontSize"]], Hold[CurrentValue[FEObject,"Graphics3DBoxOptionsClipPlanes"]], Hold[CurrentValue[FEObject,"Graphics3DBoxOptionsClipPlanesStyle"]], Hold[CurrentValue[FEObject,"Graphics3DBoxOptionsImageSize"]], Hold[CurrentValue[FEObject,"Graphics3DBoxOptionsPlotRange"]], Hold[CurrentValue[FEObject,"GraphicsBoxOptionsImageSize"]], Hold[CurrentValue[FEObject,"IsPersistent2DTool"]], Hold[CurrentValue[FEObject,"Language"]], Hold[CurrentValue[FEObject,"MarkerAspectRatio"]], Hold[CurrentValue[FEObject,"MarkerLineThickness"]], Hold[CurrentValue[FEObject,"NotebooksMenuHistoryLength"]], Hold[CurrentValue[FEObject,"PasteAutoQuoteCharacters"]], Hold[CurrentValue[FEObject,"PersistentTools"]], Hold[CurrentValue[FEObject,"Raster3DBoxOptionsPlotRange"]], Hold[CurrentValue[FEObject,"Raster3DBoxOptionsPlotRangeClipPlanesStyle"]], Hold[CurrentValue[FEObject,"RasterExploreViewRange"]], Hold[CurrentValue[FEObject,"SelectedTool"]], Hold[CurrentValue[FEObject,"ShowAutoSpellCheck"]], Hold[CurrentValue[FEObject,"ShowPredictiveInterface"]], Hold[CurrentValue[FEObject,"SyntaxColoringReasons"]], Hold[CurrentValue[FEObject,"TrackCellChangeTimes"]], Hold[CurrentValue[FEObject,"VersionedPreferences"]], Hold[CurrentValue[FEObject,AutoMultiplicationSymbol]], Hold[CurrentValue[FEObject,AutoNumberFormatting]], Hold[CurrentValue[FEObject,Background]], Hold[CurrentValue[FEObject,CellID]], Hold[CurrentValue[FEObject,CellTags]], Hold[CurrentValue[FEObject,DefaultNewCellStyle]], Hold[CurrentValue[FEObject,Deployed]], Hold[CurrentValue[FEObject,DockedCells]], Hold[CurrentValue[FEObject,DynamicUpdating]], Hold[CurrentValue[FEObject,Magnification]], Hold[CurrentValue[FEObject,NotebooksMenu]], Hold[CurrentValue[FEObject,NumberMultiplier]], Hold[CurrentValue[FEObject,NumberPoint]], Hold[CurrentValue[FEObject,NumberSeparator]], Hold[CurrentValue[FEObject,OutputSizeLimit]], Hold[CurrentValue[FEObject,PrintAction]], Hold[CurrentValue[FEObject,PrintingStartingPageNumber]], Hold[CurrentValue[FEObject,PrintPrecision]], Hold[CurrentValue[FEObject,resType]], Hold[CurrentValue[FEObject,RulerUnits]], Hold[CurrentValue[FEObject,ScreenStyleEnvironment]], Hold[CurrentValue[FEObject,ShowCellLabel]], Hold[CurrentValue[FEObject,ShowGroupOpenCloseIcon]], Hold[CurrentValue[FEObject,ShowSelection]], Hold[CurrentValue[FEObject,ShowSyntaxStyles]], Hold[CurrentValue[FEObject,StyleDefinitions]], Hold[CurrentValue[FEObject,StyleNameDialogSettings]], Hold[CurrentValue[FEObject,TransitionEffect]], Hold[CurrentValue[FEObject,Visible]], Hold[CurrentValue[FEObject,WindowElements]], Hold[CurrentValue[FEObject,WindowMargins]], Hold[CurrentValue[FEObject,WindowOpacity]], Hold[CurrentValue[FEObject,WindowSize]], Hold[CurrentValue[FEObject,WindowStatusArea]], Hold[CurrentValue[FEObject,WindowTitle]]

The list of them with object and listed second argument is too extensive to post here (I tried) but here is are the primary groups and with blanks where option names go:

Hold[CurrentValue[FEObject,{"AutoStyleOptions",_}]], Hold[CurrentValue[FEObject,{"ByteCount",_}]], Hold[CurrentValue[FEObject,{"CellChangeTimesList",_}]], Hold[CurrentValue[FEObject,{"CellCount",_}]], Hold[CurrentValue[FEObject,{"CodeAssistOptions",_}]], Hold[CurrentValue[FEObject,{"DebuggerSettings",_}]], Hold[CurrentValue[FEObject,{"Graphics3DBoxOptionsClipPlanes",_}]], Hold[CurrentValue[FEObject,{"Graphics3DBoxOptionsClipPlanesStyle",_}]], Hold[CurrentValue[FEObject,{"NotebookSecurityOptions",_}]], Hold[CurrentValue[FEObject,{"PreferencesSettings",_}]], Hold[CurrentValue[FEObject,{"PrintingOptions",_}]], Hold[CurrentValue[FEObject,{"Raster3DBoxOptionsPlotRange",_}]], Hold[CurrentValue[FEObject,{"Raster3DBoxOptionsPlotRangeClipPlanesStyle",_}]], Hold[CurrentValue[FEObject,{"WolframCloudSettings",_}]], Hold[CurrentValue[FEObject,{AutoStyleOptions,_}]], Hold[CurrentValue[FEObject,{CellBracketOptions,_}]], Hold[CurrentValue[FEObject,{CommonDefaultFormatTypes,_}]], Hold[CurrentValue[FEObject,{DigitBlock,_}]], Hold[CurrentValue[FEObject,{DigitBlockMinimum,_}]], Hold[CurrentValue[FEObject,{FindSettings,_}]], Hold[CurrentValue[FEObject,{Graphics3DBoxOptions,_}]], Hold[CurrentValue[FEObject,{MessageOptions,_}]], Hold[CurrentValue[FEObject,{NewPrimitiveStyle,_}]], Hold[CurrentValue[FEObject,{NotebookConvertSettings,_}]], Hold[CurrentValue[FEObject,{PageFooterLines,_}]], Hold[CurrentValue[FEObject,{PageHeaderLines,_}]], Hold[CurrentValue[FEObject,{PrintingOptions,_}]], Hold[CurrentValue[FEObject,{PrivateFrontEndOptions,_}]], Hold[CurrentValue[FEObject,{PrivateNotebookOptions,_}]], Hold[CurrentValue[FEObject,{RenderingOptions,_}]], Hold[CurrentValue[FEObject,{TaggingRules,_}]], Hold[CurrentValue[FEObject,{TranslationOptions,_}]], Hold[CurrentValue[FEObject,{"DialogSettings",_,_}]], Hold[CurrentValue[FEObject,{CellFrameLabels,_,_}]], Hold[CurrentValue[FEObject,{ConversionOptions,_,_}]], Hold[CurrentValue[FEObject,{PageFooters,_,_}]], Hold[CurrentValue[FEObject,{PageHeaders,_,_}]]

Hopefully this is helpful.

And then for getting this code off this page:

SEImportCode[url_]:= StringCases[Import[url,"Text"],("<code>" ~~ c : Shortest[__] ~~ "</code>" :> c)]

This will pull the raw code sections which you can then work with.
