Triggers can use a number of helper variables on the form +TRIGGERXYZ+ to

trigger target as shown in the following examples:<br/>

It is possible to set up trigger rules that basically run any operation with a
side effect you could manually do on %s. I.e. like submitting/cancelling
a job, creating/moving/deleting a file or directory and so on. When you select
'command' as the action for a trigger rule, you have the following commands at
