Its value is
1


Documentation:
Number of classes to show when completing object methods and keywords.
When completing methods or keywords for an object with unknown class,
the *Completions* buffer will show the valid classes for each completion
like this:

MyMethod

The value of this variable may be nil to inhibit display, or an integer to
indicate the maximum number of classes to display.

On XEmacs, a full list of classes will also be placed into a `help-echo'
property on the completion items, so that the list of classes for the current
item is displayed in the echo area. If the value of this variable is a
negative integer, the `help-echo' property will be suppressed.

You can customize this variable.
