Is there a way to select or deselect multiple conditional tags?

… though making a back-up, donning protective clothing and editing .mif files can shave a few minutes off the total time involved; I'm fairly confident on this, as it's something I was doing yesterday :-} Of course, working "outside" FM you won't get the helpful 'some text uses this condition' message – you'll just see everything that was hidden by a condition showing up again.
