The currently loaded text table can be switched via the preferences menu. 
Switching the text table, of course, would change both input and output. Is 
this okay?

I realize that changing the text table is rather tedious right now because of 
the number of text tables which one can choose from. One possibility would be 
to allow the -t command line option (or the text-table configuration file 
directive) to accept a comma-delimited list of text table names, in which case 
brltty could only offer those for selection.
