[orca-list] Using a braille display without routing keys

[<timothyhobbs seznam cz>]

Hello,
I have an experimental 12 cell braille display here at 
home.  It works with BRLTTY and displays text with orca just fine.  
Unfortunately at this stage of the display's development it has no routing 
keys.  Is it possible to move the braille buffer through some orca 
hotkey?  I'd like to be able to jump forward 12 characters at a 
time.  For example.  When I navigate to the File menu I might read 
"Open   Ctrl" but not be able to see the letter of the hotkey after 
the "Ctrl" I need some way to scroll the buffer to the right so I can see 
it.

I hope my question makes sense,
and thank you for your time in 
reading this,
Timothy Hobbs
