A quick tip to speed up Revit work flow is to move the Quick Access Toolbar below the menu ribbon.
It should probably be there by default. I've noticed that many users overlook it at the top. To move it simply select the option at the bottom of the drop-down.
Add almost any command to the QAT by right-clicking...
My personal favorite is to place the Type Selector drop-down on the QAT. Because the interface is context sensitive, alternatives to the object currently selected are shown immediately above the work space.
For the Playa Vista project described in the previous post, which was heavily dependent on Design options, placing the 'Pick to Edit' tool on the QAT was an incredible time saver when working among the various options in the model.
