Shortly - you can allocate the same event for several views and use the sender to find which one was clicked, then use its text or tag to do something. Example - a numerical keyboard, all the buttons have the same event and you get the value from the text of the sender.
Read the Beginners Guide and see examples there.

Note that in v2.71 there is a bug in debug mode that causes the value of Sender to be null if you pause the execution before "using" Sender.
