Brendan Upton contributed this tip for Autodesk Revit Architectural, Structural, and MEP. "Use the number pad asterisk (*) key to expand the entire tree in the Project Browser. If you would like to expand the entire tree of views and families, etc., inside the Project Browser at the same time, instead of clicking on each and every little + sign, do the following:

"Click somewhere inside the Project Browser to make it active and press the * key on the number pad. All branches of the tree will expand simultaneously. Keep in mind that it must be the * key on the number pad (above the 9). The * on the 8 key will not work."

NOTES FROM CADALYST TIP PATROL: This is a Windows feature that works in any Explorer-type listing. The asterisk will expand all folders and - (dash) will collapse them. Be sure to use the keys on the number pad, as Brendan instructs.
