I can't seem to find a way to programmatically open the special characters palette found in the Insert menu in Mathematica.
Is there a way to do this? Usually there is a frontend token one can use... but I can't seem to find one.
The following expression will open the special characters palette:
FrontEndExecute[{FrontEnd`NotebookOpen["SpecialCharacters.nb"]}] This expression was extracted from MenuSetup.tr:
{ $InstallationDirectory, "SystemFiles", "FrontEnd", "TextResources", $OperatingSystem , "MenuSetup.tr" } // FileNameJoin // FindList[#, "Special Character..."]& // First (* MenuItem["&Special Character...", FrontEndExecute[{FrontEnd`NotebookOpen["SpecialCharacters.nb"]}]], *)
