+Distinctive bullets are not cycled when topics are shifted or
+otherwise automatically rebulleted, so their marking is
+persistent until deliberately changed.  Their significance is
+purely by convention, however.  Some conventions suggest
+themselves:
 
- ... for example.  (`#' typically has a special meaning to the software,
-according to the value of `allout-numbered-bullet'.)
+ `(' - open paren - an aside or incidental point
+ `?' - question mark - uncertain or outright question
+ `!' - exclamation point/bang - emphatic
+ `[' - open square bracket - meta-note, about item instead of item's subject
+ `\"' - double quote - a quotation or other citation
+ `=' - equal sign - an assignement, equating a name with some connotation
+ `^' - carat - relates to something above
 
-See `allout-plain-bullets-string' for the selection of
-alternating bullets.
+Some are more elusive, but their rationale may be recognizable:
+
+ `+' - plus - pending consideration, completion
+ `_' - underscore - done, completed
+ `&' - ampersand - addendum, furthermore
+
+\(Some other non-plain bullets have special meaning to the
+software.  By default:
+
+ `~' marks encryptable topics - see `allout-topic-encryption-bullet'
+ `#' marks auto-numbered bullets - see `allout-numbered-bullet'.)
+
+See `allout-plain-bullets-string' for the standard, alternating
+bullets.

-reconcile to changes of this value.
