#!N As you create a visual program, you may have inputs 
whose values are subject to frequent change. You can use interactors 
as an easy method for controlling those input values.  #!F-adobe-times-medium-i-normal--18*   Interactors 
#!EF , which appear only in Control Panels, are the interactive 
devices that you use to manipulate inputs to a visual program 
in order to change the image that is produced (see  #!Linterac,dxall409 h Using Interactors  #!EL  
for detailed descriptions). #!N #!N  #!F-adobe-times-medium-i-normal--18*   Interactor stand-ins #!EF are used 
to indicate which input to a module a given interactor is 
to control. While you are building the network in the VPE, 
you select interactor stand-ins from the tool palettes and place them 
on the canvas, as you do with other tools. Like any 
tool, the output of an interactor stand-in can be connected to 
more than one input. Interactor stand-ins are named, in general, after 
the type of data they output: #!N #!I0 #!N #!N #!I0

visual programmer to associate comments with each Control Panel. To access 
these comments, use the  #!F-adobe-times-bold-r-normal--18*   On Control Panel #!EF option of 
the  #!F-adobe-times-bold-r-normal--18*   Help #!EF pull-down menu in the Control Panel about

Control Panel, the  #!F-adobe-times-bold-r-normal--18*   On Control Panel #!EF option is grayed 
out. #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*   Next Topic #!EF #!N #!N  #!Lcpi,dxall381 h Building Control Panels  #!EL
