Use this setting to define the operation of the left scroll buttons. The
available options are "Scroll display", "Move by line", "Move by character",
"Move by paragraph" and "Move by sentence". Use "Space" to cycle among
the options.
If you set the value to "Scroll display," the left-scroll buttons scroll by
previous/next Braille display length. Pressing the left-up scroll button, scrolls
to the previous Braille display length, and pressing left-down scroll button,
scrolls to the next Braille display length.
If you set the value to "Move by line", the left-scroll buttons scroll to the
previous/next line, similar to pressing “up arrow button” or “down arrow
button” on the Qwerty keyboard.
If you set the value to "Move by character," the left-scroll buttons move to the
previous/next character on the Braille display, similar to pressing “Left arrow
key” or “Right arrow key”.
If you set the value to "Move by paragraph," the left-scroll buttons can be
used to move to the previous/next paragraph, similar to pressing "Ctrl-up
arrow button" or "Ctrl-down arrow button".
If you set the value to "Move by sentence," the left-scroll buttons scroll to the
previous/next sentence, similar to pressing "Ctrl-Alt-Left arrow button" or
"Ctrl-Alt-Right arrow button" on the Qwerty keyboard.
