[orca-list] orca preferences

[Christopher Moore <christopher h moore verizon net>]

Hello,
Here's a real puzzler.
After starting orca, I get the preferences buttons.  When I hit the 
keypad-8 key I hear
Preferences Quit label Help
I think we all know what the three buttons are all about.  What does the 
word "label" indicate?

A related question is that navigation between the buttons can be done 
with the tab (as expected) but also with the arrow keys (why).
