Hi Becky;

EJ	You're right, Tab does close enough to the same thing as 
Cntrl+Dn Arrow that I have no problem removing it [Cntrl+Dn 
Arrow] from the spec.

EJ	It would depend on how the Developer coded things I'd imagine 
but on first blush I'd say Cntrl+F10 only works to call up the 
menu if the popup is "attached" to [extends] the area that has 
Input Focus. But my guess is a Developer could just as likely 
make it so pressing Cntrl+F10 calls up the same menu when Input 
Focus is in the Pane Content or Pane Header. So the answer seems 
to boil down to "it depends" for me, what do you think?

EJ	Same as above. Having said this, an edit of the spec 
clarifying these 2 descriptions probably makes sense.

EJ	I caught this same oversight last night while speaking to the 
developer of our Accordion Component. I assigned Enter as the way 
to toggle the Pane open or closed; Input Focus must be on the 
Pane Header for Enter to work as the toggle.
