 No, it won't be executed since the link has the FORM_LINK_TYPE type, and
these are filtered out.

 Yes, I agree.

  Since LYK_ACTIVATE is called, the same code will be executed independent of
the keyt that cause execution.

  Yes, I think that it makes sense to keep original behaviour too.

  Seems these are not required then.
  Thanks for your notes. Please feel free to elaborate on this subject.
