# Arrange interactions The position of the variables and their connecting arrows can be changed by moving them around with the left mouse key pressed.
This moving function is automatically controlled and allows to arrange the effect system quickly without losing the established connections. The mouse arrow can grip the line between the variables either at the top or at the end but also at the curved corners (which is of help if two arrows lie one on top of the other or cross a variable).
If two arrows are put at the same connecting point of a variable number, the program automatically shifts the first arrow to another place.
While working in the function CONNECT the moving is only possible when the white mouse arrow in the grey bar is activated.
Via the Button "Arrange network" (via "Connect") the program arranges the network automatically (the action can be repeated several times). The automatically generated layout has to be accomplished manually.
