+    Describes which events should trigger an event_variant.
     The corresponding event_variants and their actions are declared in DisplayConfig.xml (in /Resources/Interactions).
     If no event_variant is specified here, this action is disabled during the activation of a tool.
+    So if an action here conflicts with you tool you can comment out this section.
     ! Alternatively you can also just change the event description, so that the actions are triggered by different mouse/key events
     during Tool use. !
+    Refer to 'How to create a Config-File' http://docs.mitk.org/nightly-qt4/Step10Page.html for details.
