I am not sure I understand the best way to “float” the intersections of drywall ceilings and walls. Do you leave the ceiling panel edges loose all the way around the room or just at the corners? Do the walls get screwed all the way up or just within 7 to 8 inches of the ceiling?

Sounds like you are trying to avoid a truss uplift problem.
You do not screw the d/w to trusses within the two feet of a wall to corner intersection, thus it is floating. When you hang the walls, you pin the ceiling sheat to the bottom of the truss with the upper sheet. Screw the top of the wall piece as you normaly would, tape and finsh. Since the ceiling board is not attached to the truss within two feet of the wall, if you get truss uplift it is suppose to be able to flex enough ro keep from splitting the tape or cracking the joint compoud.
Are clips optional?
Tom
I have never used them, but it seems reasonable that they would hold the floating ceiling edge to the wall panel a little more than mud and tape.
We have been using clips for the past 5-8 years. Not only do they hold the drywall in place but they are necessary to help align adjacent sheets. We also use them on wall intersections.
When do you decide you are going to have truss uplift , or is this your common way of building ?

"When do you decide you are going to have truss uplift...?"
Any house with roof trusses that's in an area of the country that requires heating can have truss uplift. Her's a thread about it I did a while back with a lot more info and B.S.:
Truss uplift
BTW - I almost called you a "goat roper" once, since you're from Arkansas. But I wasn't sure if that was PC, or if it's just people from Oklahoma that called themselves goat ropers.........Everything can be filed under "miscellaneous."
The slotted anchor, do you need to put in one on each side of the truss or just one at each attachment point?
Tom
I don't see any reason to use them on both sides. All you're trying to do with them is hold the wall in position. Bumpersticker: If you can read this, I've lost my trailer.
I was thinking of it being similar to toe nailing, thanks.
Tom
All trusses, since I built my inlaws home in 91. I did not hang or finish the board, but I sure heard about the cracked corners and tape pulled loose.
Attached you should find some pictures which might help explain it better.
As far as I'm concerned, clips are optional. I prefer wood blocking between the trusses. The blocking is attached to the top plate of the wall, and sticks over the edge. Then the drywall can be screwed to the blocking.
