The Selector panel displays the list of Reports (Functions, Processes) that are available for opening in the Workspace. The panel shows a hierarchical tree of procedures, with the following markings:
Procedures that are already opened and loaded into the Workspace are shown in a disabled ("grooved") color.
Procedures
that have been saved with syntactical errors are shown in bold font, with
the red bullet 
as
the node marker. Such procedures are not executable, and if they are included
into other procedures as components, the higher-level procedures too become
non-executable until the problem is fixed.
