Ribbon - 2010 - Shortcut Key

Question
I'm trying to learn the Ribbon in Access 2010
I have a lot of it under control, but I don't understand the KeyTip (Short Cut Key?) in the XML aren't working as >>>I<<< expect.  
>>>I<<< expect Alt d would bring up the Print Dialog.  (See below graphic)

Facts
 If I have the below XML in my USysRibbons table (along with more xml)  why do the key tips not work as I expect?  If you look at the XML there are two Keytips / 1 a Q and 1 a d.

If you look at the top of the two graphics
  1) When I hold down the Alt key I see F on my quick Print /  Nothing on Print Dialog
  2) If I then click F it takes me to the File tab on the Ribbon
  3) If I click Y + 1 (which is not in my xml)  it shows me the shortcut keys I expect (see bottom Graphic)
  4) at this point I can click d and it works like expected (shows the Print Dialog screen)


        <group id="ListCommands" label="Print">
           <button idMso="FilePrintQuick" keytip="q" size="large"/>
           <button idMso="PrintDialogAccess"
                   label="Print Dialog"
                   keytip="d" size="large"/>
        </group>
        <group id="ListCommands" label="Print">
           <button idMso="FilePrintQuick" keytip="q" size="large"/>
           <button idMso="PrintDialogAccess"
                   label="Print Dialog"
                   keytip="d" size="large"/>
        </group>

One Other Related Question if you are so Inclined
I obviously misunderstand the below webpage
I thought that if you put      label="Print &#38;Dialog"  in the xml
the "D" in Print Dialog would be underlined and Alt D would be a shortcut key.

I got this from  http://www.accessribbon.de/en/?Access_-_Ribbons:Keytips_in_Ribbon_Controls

Thanks in advance for your Help.
