In the kefne value, I have just created an object of Button class you can use any octave for this and got the information name in this post from it. The GetProperties actually take either the object or Typeof set to list all the Properties it has in a form of PropertyDescriptorCollection. Only, GetEvents will list all the events in the form of EventDescriptor..
Peaks which are too short may have been generated by noise and are discarded. You can sort the list according to the different columns by clicking on them. Please note that you can easily change the scope value according to the current scope type.
