[BRLTTY] Changing key mapping to copy text to clipboard

[Christian Schoepplein]

Hi,

with a Braillestar from Helptech it is possible to copy text which is 
located in one line into the clipboard by pressing the routing keys that are 
located at the beginning and end of the text at the same time. This is a 
very nice and convenient feature and it would be so great to have this also 
for the el40c and el80c from Papenmeier. Can I reconfigure the keymappings 
for the el40c and el80c somehow to get this behaviour?

Ciao and thanks,

  Schoepp
