I have searched high and low for documentation on how to use this feature. While the loop I could write would be simple and take no time, I really would like to learn how to use this.

Basically I have a class, say, Widget, with a Save() sub that returns nothing. So:

Dim w as New Widget()
w.Save()

basically saves the widget. Now let's say I have a generic collection List(Of Widget) name widgetList(Of Widget) and I want to run a Save() on each item in that list. It says I can do a

widgetList.ForEach([enter Action(Of T) here])

....but how in the F does this work??? There is no documentation anywhere on the intrablags. Help would be much much appreciated.
