Here are the rules for where to find the characters:
ALPHABETIC CHARACTERS:
All capital letters face LEFT.
All lower-case letters face RIGHT.
NUMBERS AND PUNCTUATION
Keyboard mapping was a little difficult for punctuation; in general, the normal keys to produce a number or punctuation mark will produce a letter facing LEFT. The RIGHT-facing versions add the option key (e.g., pressing 3 gives you a left-facing 3; pressing option 3 gives you a right-facing 3). However, for PC users of the font, these are high ASCII characters that you have to produce using the NUM LOCK/ALT shuffle. Therefore, keep in mind the following rule:
ALL NUMBERS AND PUNCTUATION FACE LEFT.
Right-facing versions of numbers and punctuation are at the following ASCII values:
0 - 188
1 - 193
2 - 170
3 - 163
4 - 162
5 - 176
6 - 164
7 - 166
8 - 165
9 - 187
. - 179
, - 178
' - 190
" - 174
! - 218
? - 192
& - 224
$ - 221
There is also a combined apostrophe-S ligature on the Mac Keyboard at option-s and shift-option-s; the ASCII values for this ligature are 167 and 234, respectively.
BLANK SECTIONS OF FANFOLD
The spacebar produces only white space; to get a blank section of fanfold, use left parenthesis, left bracket or left brace for a LEFT-facing blank fanfold; use right parenthesis, right bracket or right brace for a RIGHT-facing blank piece of fanfold.
