There are several ways that you can move a variable into a zone:
• To move a variable from one zone to another, click and drag it from the old zone into the new zone.
• To replace a variable in a zone, drag the new variable over the old one.
• To switch a variable from one zone to another, right-click the variable in the zone that you want to move and select Swap. Then, select the variable that you want to switch places with.
• To merge variables on the same axis, see Merge Variables on a Common Axis.
To remove a variable, drag it into empty space, or right-click the name of the variable in the zone and select Remove.
