commit ab0b27c7545c0b58b4eddbfa2f13b9956ba06998
Author: Joanmarie Diggs <jdiggs igalia com>
Date:   Fri Nov 30 01:37:37 2012 -0500

    Fix for bug 689327 - Eliminate the Main Window"
This commits meaning entire not possible presenting Orca main window 
(not possible activating into main window with settings, about, help and 
quit buttons)? If this is the case, how can possible presenting Orca's 
about dialog or activating Orca help? Always need goto preferences 
dialog, activating the help button, switch back preferences dialog and 
close the preferences dialog? If this is the case, not possible 
associate a central keybinding to present Orca's help content any time 
(for example Orca modifier+SHIFT+O keystroke)? In laptop layout Orca 
modifier+O and Orca modifier+CTRL+O are reserved keybindings for flat 
review. Possible have better key binding this purpose with equals easy 
to press with desktop and laptop layouts, but I not have now better ydea.

This commit meaning Orca always quitting without confirmation if the 
user press Orca modifier+q keystroke?
