Sometimes the smaller, less significant features are the best. In Revit 2014 you now have the access to the following selection tools which are located in the bottom right of the interface.
These tools are very simple but can drastically increase productivity while working with linked CAD models, Linked Revit Architecture or MEP models. Below you can see the selection tools and their use.
Selecting elements by face is really useful whilst trying to select and edit a floor in a plan view. When enabled, this simple tool allows you to pick the floor by face.
I tend to pin objects such as grids and levels and the selection of pinned elements is another good one to manage.
As I said, simple but really useful!
Hope this helps,
