 ### Parameter Info
 
 The IntelliSense **Parameter Info** option opens a parameters list that provides information about the number, names, and types of the parameters that are required by a function. The parameter in bold indicates the next parameter that is required as you type a function.
 
 The parameter list is also displayed for nested functions. If you type a function as a parameter to another function, the parameter list displays the parameters for the inner function. Then, when the inner function parameter list is complete, the parameter list reverts to displaying the outer function parameters.

 ### Quick Info
 
 As provided by the language service, you can see **Quick Info** for each identifier in your code. Some examples of identifiers are input, output, an intermediate result set, or function. When you move the mouse pointer over an identifier, its declaration is displayed in a pop-up window. The properties and data schemas for inputs, if configured, and intermediate data set are shown.
