Thanks for the clarification, but in that case should KernelExecute
menu items also work?

I have made three examples to illustrate the question.

(For readers, these menu modifications only persist for the current
front end session.)

The first one adds a MathGroup link to the Help menu, and works
fine, (at least with Chrome).

  "SelectionHelpDialog", {Delimiter, 
   MenuItem["&MathGroup Archive", 
         "";], None}]}], 
    MenuKey["M", Modifiers -> {"Control", "Shift"}]]}]]

The second example adds a custom function at the same location on
the Help menu.  The MenuItem works if it is included in
but when added through AddMenuCommands it produces the message
"Could not process unknown packet "CreateDialog"."
  "SelectionHelpDialog", {Delimiter, 
   MenuItem["Custom Function version 1",
     CreateDialog[{TextCell["Click OK to close"],
    MenuEvaluator -> Automatic]}]]

The third example is a roundabout way to achieve what the second
example attempts.  It works for the function demonstrated, but it
would not work for OptionsExplorer[] which need to access the
current front end selection.  (OptionsExplorer seems to have some
obsolescence problems, by the way, before anyone spends time.)

  "SelectionHelpDialog", {Delimiter, 
   MenuItem["Custom Function version 2",
       RowBox[{RowBox[{"CreateDialog", "[", RowBox[{"{",
                 "[", "\"\<Click OK to close\>\"", "]"}], ",",
               RowBox[{"DefaultButton", "[", "]"}]}],
             "}"}], "]"}], ";",
         RowBox[{"NotebookClose", "[", "]"}]}]],
    MenuKey["F", Modifiers -> {"Control", "Shift"}]]}]]

Is there some way to run KernelExecute with AddMenuCommands?

Thanks, Chris
