Several of the mentioned key values apply to US keyboard layout, not to others. ----- Original Message ----- From: "Catherine Thomas" <braille@xxxxxxxxx> To: <duxuser@xxxxxxxxxxxxx> Sent: Sunday, February 10, 2008 3:54 PM Subject: [duxuser] Re: new braille symbols Susan, The subject of alternative symbols came up on the Paperless Braille list recently. In addition to the tilde for dots 4-5 you can also create: dot 4 using either the at sign (shift plus 2) or the accent grave key. This key eliminates the dot 7 on the refreshable braille displays. You can create dots 2-4-6 by using either the left bracket key or shift plus the left-bracket key, eliminating the dot 7. The right-bracket key creates dots 1-2-4-5-6 as does the shift plus the right-bracket key eliminating the dot 7. As a result of these alternative keys, the only remaining key of those used to display the 63 braille characters on the standard keyboard that would still show a dot 7 on the refreshable braille display is the underscore which is used to create dots 4-5-6. According to an informed source who dabbles in codes, there is a character somewhere in the extended ASCII set that would produce dots 4-5-6 but it's too complex to make it part of the standard braille table. Some Linux braille table for brltty has already conquered this but I'm not up on how. I hope this info benefits somebody while it bores all the other bodies.
