We have created a Grade 2 Braille config that you can get here:
twiddler_Braille_Grade_2.cfg (1.1 KB)
and a mirrored version here:
twiddler_Braille_Grade_2_Mirrored.cfg (1.0 KB)
Updates to the config from the original Braille Configurations post include:
The farthest key from your hand on the bottom row (ENT / D for mirrored) was picked as space, as it was the easiest to press. The middle key is backspace and the closest key is return.
Number chords are modified with the num-lock. Typing the numerical sign produces the equivalent to a pound symbol (#).
Grade 2 Braille abbreviations have control as a modifier. Control was picked because it is close to the thumb and is easy to use.
Grade 2 letter combinations (ch, th er, etc.) are used without modifiers, although double letters still use the control modifier.
All punctuation is can be typed with the use of the shift key or without it (except *) as well. Opening quotation marks were omitted, as they share the same chord as ?, so the chord for a closing quotation mark should be used for all quotation marks.
The brackets have been replaced with | as brackets are contextual in braille, and | can be used in the place of both opening and closing brackets.
