Reset rally point and camera

In several occasions during the game there is a need to change the rally point of all army-producing buildings.

There are several kinds of rally setup: norally, rally on area, rally on unit, rally on area-unit.

For the rally on area, resetting involves the following action:

A) make sure that the current selection contains the army-producing buildings whose rally point you want to change.

B) shoot the desired location, by mouse-scrolling, edge-scrolling, keyboard-scrolling, or clicking on the minimap.

C) click the right mouse button in the middle of the screen, on the ground.

D) execute the key combination to set camera location.

There are many ways to order these actions: ABCD, ABDC, BACD, BADC, BDAC.. the only constraints are that B comes before D and A comes before C.

If you are terran, there is a risk that this operation interrupts the relocation of a building. Any flying building in the selection will interpret action C as a move command.

In order to mitigate this risk, there are three techniques:

1) skip this step altogether. If you suspect that there are any flying buildings, just don't do this.

2) use the "set rally point hotkey" instead of right-click, This has the drawback that it costs a hotkey slot.

3) at step A, make sure that the current selection does not contain flying buildings, by deselecting, via the information panel, all those buildings that could be flying. In the information panel buildings that are flying display no queue grid. Unfortunately, buildings that are building add-ons also display no queue grid. Therefore, flying buildings and buildings that are building add-ons cannot be distinguished, and you will have to deselect them all. This workaround will fail to set the rally point of buildings that are building add-ons.
