-One exception to this rule is @code{\} itself, because @code{\\} has

-command.
+As to the last three characters, to get a tilde in the text body font
+use @code{\~@{@}} (omitting the curly braces would result in the next

-Finally, you can access any character of the current font once you
-know its number by using the @code{\symbol} command. For example, the
-visible space character used in the @code{\verb*} command has the code
-decimal 32, so it can be typed as @code{\symbol at domain.hid@}}.

+You can access any character of the current font using its number with

+You can also specify numbers in octal (base 8) by using a @code{'}
+prefix, or hexadecimal (base 16) with a @code{"} prefix, so the previous
+example could also be written as @code{\symbol at domain.hid@}} or
