The Purpose of Collections
Collections in VBA always refer to collections of objects. The feature of collections in Excel groups similar objects together into one group. Not only does this help you as a user make your way through the many codes that will eventually pile up, but it will also help Excel to find the right object at the right time. You are free to organize and rename the collections however you like, just make sure that you always make the collections clear and to the point so that when you want to use them you know exactly which collection is referring to which part of the Excel use for you.
