-----------
Clicking and dragging an a series of toggle buttons with the same function toggles them all to the same state. Works for lots of different kinds of toggle buttons, such as the layout buttons, buttons in the outliner, and listbox buttons. State variables are stored in G, which is perhaps not appropriate, but is the best place I've found so far to store such things.
