6 . Using the Braille keyboard
This chapter provides an overview of the Braille key combinations that emulate
keyboard function keys. There are two types of function keys; chord commands to
emulate keyboard function keys and prefix chord commands to emulate function key
combinations.
6.1. Chord commands
Chord commands are Braille key commands that are combined with the space bar.
These chord commands are used to emulate keyboard function keys such as Home,
End, Backspace, Delete and Escape. Please note that these commands can only be
used with screen readers that do not support direct Braille input. JAWS, Dolphin
Supernova, Voice Over and BrailleBack have their own Braille commands for these
functions. Please refer to the screen reader documentation for the list of Braille
commands for these functions.
