[BRLTTY] Need help remapping display

>Now, I see functions are mapped externally through files in /etc/brltty. 

Yes. They're called key tables. The one you probably want to update for the 
Brailliant is called "brl-bm-display6.kti".

>How could I assign some routing key combinations to certain functions? How 
>does one declare specific RoutingKey combination? 

As you've no doubt already observed, you can refer to an arbitrary routing key 
by "RoutingKey". You can refer to a specific routing key by adding a dot and a 
number (starting from 0). The leftmost routing key, therefore, is 
"RoutingKey.0", and the rightmost routing key (assuming a 40-cell display) is 
"RoutingKey.39".

You may wish to read the file "README-KTB". It's a little out-of-date, but 
it'll still hopefully be helpful. Nothing in it is old and no longer usable. 
It's just that documentation for some new features hasn't yet been added to it.

>What is the meaning of the operator ! , 

It means that the function is invoked as soon as you press the key. Without it, 
the function isn't invoked until at least one key is released.

>as in RoutingKey+!RoutingKey?

That means that the function is invoked as soon as the second routing key is 
pressed.
