E-Studio has three primary uses for the Colon (":") character.
- Colon Syntax 
- A position placeholder for a sub-object.
- E-BASIC: Using Labels in InLine Script 
The Colon Syntax method is used to sample multiple items from one list. See the sample above for more information on this feature.
When using a FeedbackDisplay or Slide, you may use an Attribute reference for Frame properties which affect its placement in E-Studio. These are placeholder values as the actual value is assigned during runtime. For example, we want our SlideText to randomly be displayed in one of three X positions. This is set by an Attribute called "XPos" in our List to randomly select 25%, 50%, or 75%. When you enter [XPos] for the X Position value, you will note it is placed in the center by default and reflected by the value after the colon.
You can modify this placeholder value to reflect a location of your choice in E-Studio.
Colons follow the name of a Label in script. See the above article for an example of this syntax.
