Bug 680259

Problem Description:

Following the guidelines here: 
http://library.gnome.org/devel/accessibility-devel-guide/nightly/id2915148.html.en

and the general tests located on table 2-2 here:
http://library.gnome.org/devel/accessibility-devel-guide/nightly/gad-checklist.html.en

rhsm-gui fails to meet some of these keyboard accessibility guidelines.  While it may not be necessary to meet all of the accessibility rules outlined in the links above to their fullest extent, I believe an overall consistency should be achieved, and an attempt should be made toward usability in this area.  This is especially important in firstboot where a mouse may not be available during installation time (and the fact that the rest of the graphical installation process follows these guidelines quite well).

Examples:
- In the System Registration dialog the 'Cancel' button can be accessed via Alt+c, but the 'Register' button and the autosubscribe checkbox cannot be accessed quickly by a similar keyboard shortcut.

- In the  'My Subscriptions' tab when you have a subscription highlighted, tabbing out of this to the next element tabs to several non-viewable elements and keyboard input is ignored completely before the tab order finally gets to the 'Unsubscribe' button.

- In the same tab, the 'Subscription Details' cannot be accessed or scrolled with the keyboard.
- The contract selection dialog has keyboard shortcuts to cancel, but not subscribe.

- In the 'All Available Subscriptions' tab, the subscription details can selected (via the items shown under bundled products), but scrolling down with the keyboard through this field doesn't move the scrollbar down and elements off the viewing window are highlighted.

- Tabbing out of the products list in 'My Installed Software' seems to cycle to a non viewable element, and keyboard navigation is ignored.

- There is no default action when registering, so hitting enter after you enter in your login credentials does nothing.

- The buttons under 'tools' should probably have a ALT+<key> shortcut associated with them.
