Description:
executing HELP SELECT produces:

...
  In the WHERE clause, you can use any of the functions and operators
  that MySQL supports, except for aggregate (summary) functions. See
  [HELP =].
...

However, "HELP =" is about the comparison operator itself, not about the WHERE clause. Also, it is a bit confusing to use = as the name of a HELP topic.

How to repeat:
Run HELP SELECT

HELP = seems to be a valid command in the mysql command-line client:

astraia~> mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 32
Server version: 5.1.23-rc-log MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> help =
Name: '='
Description:
=

Equal:

URL: http://dev.mysql.com/doc/refman/5.1/en/comparison-operators.html

Examples:
mysql> SELECT 1 = 0;
        -> 0
mysql> SELECT '0' = 0;
        -> 1
mysql> SELECT '0.0' = 0;
        -> 1
mysql> SELECT '0.01' = 0;
        -> 0
mysql> SELECT '.01' = 0.01;
        -> 1

mysql>                                       

Please explain what the Manual/the help table entry should say instead of pointing to HELP =.

Resettting to Verified.  "HELP =" is indeed a valid help command, but [HELP =] isn't the correct reference for aggregate functions.

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly, and will be included in the next release of the relevant products.

Modified the method for mapping cross references to HELP topics. It turns out there were a number of incorrect mappings.
