[orca-list] Do you think these new commands would be useful?

[Dattatray Bhat <bhatdv gmail com>]

To use a screen reader efficiently, the user needs good knowledge of keyboard shortcuts. In a given context, he should quickly recall the appropriate keyboard shortcut. For a new user who has yet to master the shortcuts, a command to list the available shortcuts would be very helpful. However, Orca currently doesn't have such a command.

I have created an enhancement request (Bug 616820) and submitted a patch adding two commands. The change works as follows -
The user can enter 'List Shortcuts' mode by pressing Orca + H(double click). In this mode, the user can select a group of shortcuts. Pressing '1' lists Orca default shortcuts. Pressing '2' lists Orca shortcuts for the application under focus. After selecting a group, the user can navigate and hear the shortcuts by pressing 'Up/ Down', can toggle to the other group by pressing '1' or '2', or can exit 'List Shortcuts' mode by pressing 'Escape'.

Kindly give your inputs on the following -
1. Do you think these new commands would be useful?
2. If yes, do we also need commands to list Gnome shortcuts, Open Office shortcuts, Firefox shortcuts etc.?
3. If yes, in which files are the keybindings for Gnome, Open Office, Firefox etc. stored?

Regards.
