Indeed, here's some more macro examples:
$HOSTDOWNTIME:myhost$                       <--- On-demand host macro
$SERVICESTATEID:novellserver:DS Database$   <--- On-demand service macro

You can also use hostgroups/servicegroups with a delimiter (delimiter
should be ',' for check_cluster)

# $HOSTMACRONAME:hostgroup_name:delimiter$
# $SERVICEMACRONAME:servicegroup_name:delimiter$

See the Nagios documentation for more details...
