Gully Foyle, over on the Google Help Forum, has posted a great idea to speed up the tedious process of reversing faces.
In the post, it is pointed out that the Push/Pull Tool is unique in that it selects entities when you simply hover the mouse over them. By assigning a shortcut key to Reverse Faces, you can select the Push/Pull Tool, hover over the face you want to reverse, and press the shortcut. Ingenious!
UPDATE: I've since heard from Gully that he was not the thinker-upper of this idea, rather he remembered reading it in the Pro Forum.
