This allows you to use six keys on your regular PC Keyboard, plus the space bar, to input braille directly to DBT.
If necessary, you may change the keys used for six-key braille entry.
You might for example wish to use the CXZ BNM keys instead of FDSJKL.
Note: the sequence above represents dots 321 456 - specifically in that order.
The method for changing this has changed from 10.6 and above and is now done through the Global: View Preferences dialog
