1. If the first and/or last event numbers are defined, then the filter will select events in this range only.

2. If the evtstring is defined, only listed events of event ranges will be selected. For example, the evtstringparameter can be defined as

   bgColor #F7F7ED
   2,5,11-15,20-25,29,30

   that means the list of events:

   bgColor #F7F7ED
   2 5 11 12 13 14 15 20 21 22 23 24 25 29 30
