Describe the feature you want to add

Most of the time we tend to reuse Environment Variables in our API request, Sometime it might happen we misspell the variable name and due to the same request gets failed, if we can have a feature that will display the list of available Environment variables defined, it will not only speed up the parameterization but also it will make it error free.
