Which values do f:ajax render accept

In JSF I can update components with ajax:

<h:commandButton ...>
    <f:ajax render="@form" />
</h:commandButton>

I found some of these values in the web: @form @this @parent @none @region @all.

Is there a complete list of the standard values which come with <f:ajax>? And do these values have a special name which I could lookup?

Just look in <f:ajax> tag documentation.

render

Evaluates to Collection<String>. The clientIds of components that will participate in the "render" portion of the Request Processing Lifecycle. If a literal is specified the identifiers must be space delimited. Any of the keywords "@this", "@form", "@all", "@none" may be specified in the identifier list. If not specified, the default value of "@none" is assumed. For example, @this clientIdOne clientIdTwo.

The others you mentioned (@region and @parent) are recognizable as from PrimeFaces <p:ajax>. So if you were actually facing problems while trying that on <f:ajax>, you should now understand why.
