[orca-list] Multiple App Profiles

[Ted <orangegrovebear gmail com>]

As far as I can find, when I set up an additional profile and switch to 
it in Orca, the changes do not apply to the application-unique 
preferences, such as Firefox. However, an application-unique preference 
dialog has no option for multiple profiles in the general settings. The 
only way I've found to do this is to manually replace the app 
configuration file in the app settings directory and restart Orca. Is 
there an easier way that I'm overlooking?
I would like to have multiple configurations for apps to change 
app-specific key bindings on the fly by cycling through the profiles. 
For example, to change the up/down and left  right arrow keys to apply 
to table navigation without having to hold down the alt and shift keys, 
then switch the same keys to apply to structural navigation, such as 
headings and links, or words and lines.
Thank you.
