Several of the mentioned key values apply to US keyboard layout, not to 
others.

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.
