A message for a specific component, such as a warning or error. If an <apex:message> or <apex:messages> component is not included in a page, most warning and error messages are only shown in the debug log.

A component that provides support for invoking controller action methods directly from JavaScript code using an AJAX request. An <apex:actionFunction> component must be a child of an <apex:form> component.

The list view picklist for an object, including its associated list of records for the currently selected view. In standard Salesforce applications this component is displayed on the main tab for a particular object.
See also: <apex:enhancedList>.

A read-only display of a label and value for a field on a Salesforce object. An <apex:outputField> component respects the attributes of the associated field, including how it should be displayed to the user. For example, if the specified <apex:outputField> component is a currency field, the appropriate currency symbol is displayed. Likewise, if the <apex:outputField> component is a lookup field or URL, the value of the field is displayed as a link.
Note that if custom help is defined for the field in Setup, the field must be a child of an <apex:pageBlock> or <apex:pageBlockSectionItem>, and the Salesforce page header must be displayed for the custom help to appear on your Visualforce page. To override the display of custom help, use the <apex:outputField> in the body of an <apex:pageBlockSectionItem>.
