Public Function FullKeyboardAccessEnabled() as Boolean
  #If TargetMacOS
      Declare Function NSClassFromString Lib "Cocoa" (name As CFStringRef) As Ptr
      Declare Function GetSharedApplication Lib "AppKit" Selector "sharedApplication" (target As Ptr) As Ptr
      Declare Function IsFullKeyboardAccessEnabled Lib "AppKit" Selector "isFullKeyboardAccessEnabled" (target As Ptr) As Boolean
      Dim AppClass As Ptr = NSClassFromString("NSApplication")
      If AppClass <> Nil Then
        Dim AppObject As Ptr = GetSharedApplication(AppClass)
        If AppObject <> Nil Then
          Return IsFullKeyboardAccessEnabled(AppObject)
        End If
      End If
    Catch Err As RuntimeException
      Return False
