Mac: Expand all folders in finder list view mode

Have you ever spent the time clicking on each level in a Finder window to expand the tree below? Have you ever wish that there was a way on your Mac to expand all the subfolders below a folder? While there isn’t an option on the menu you can accomplish this by pressing and holding the Option button while you expand (click the triangle to the left of the folder) a folder. Pressing and holding the Option button as you click will expand all the folders below a folder while in list view mode.
