How do I do 6-key Braille input? Does Mac OS X have a facility for 6 key (Perkins) Braille typing? That is using F, D, S, J, F &amp; L to type in the various Braille cells (mapping respectively to ⠁, ⠂, ⠄, ⠈, ⠐&amp; ⠠) on the keyboard. I don't want to have to use the character palette as that would really slow me down. If OS X doesn't have it out of the box, what 3rd party tools are good?

An answer for 8-key input is also acceptable.
Just recently out I think, Braille Writer for OS X:
