Right now, when there are only two choices, our toggle commands play an on tune 
or an off tune for confirmation. How should confirmation of selection work when 
there are more choices than just two?

Yes, it would be possible, but we should think about how best to design it.

The easiest way would be to internally restart brltty after selecting the 
configuration file. This, of course, would also mean that the braille driver 
would restart. Is that acceptable, or should the code be reworked to allow 
reloading a subset of the configuration settings and then only restarting the 
bare minimum (which, in your case, would be just the speech driver)?

something else to consider is the fact that, currently, command line options 
override configuration file settings. What if the selected configuration file 
has settings which are overridden by command line options? In that case, which 
should take effect?

How should configuration file selection be performed? Would you want to go into 
the preferences menu, find the right setting, and select it? Another approach 
would be to implement a key combination which would be used in conjunction with 
a routing key, where each routing key would select a different configuration 
file. Maybe there are more alternatives which I haven't thought of.
