While using a Brailliant or other display running Humanware firmware version 2.0, after pressing space with dots 1-7 to emulate the command key, it is no longer possible to follow this up with a letter such as command n

For applications like mail and Notes where iOS allows for Bluetooth keyboard shortcuts, you can also emulate he command key on a braille display with space and dots 1-7. If you wish to create a new email, for example, you could thus press space with dots 1-7 followed by n to use this shortcut on a display... No longer if you are using a Brailliant BI20X, BI40X, Chameleon, NLS E-Reader or BrailleONE. This does not impact users of the Mantis.
