I click on the number or the name of the resource belongs to this area I want to lear

Hello;

Scheduler component to record an event I click with the mouse somewhere on the non-resource.
I click on the number or the name of the resource belongs to this area I want to learn.
But somehow I could not.
But I belong to a resource name or number of the event, but I click on an empty resource I want to know the name or number.
Please could you help.
Very thanks...
