This dialog box displays options that guide what the Relation Window will pay attention to.
Automatic Symbol Tracking
As you move your cursor around in a source file, the Relation Window "tracks" the symbol under the cursor, or around the cursor. This group of options tells the Relation Window what to track.
Off
Select this to disable automatic symbol tracking.
Track selected symbol (i.e. under cursor)
Select this to have the Relation Window look up the definition of the symbol currently under the typing cursor.
Track the enclosing function or class
Select this to have the Relation Window show the definition of the function or class that contains the typing cursor. This is useful to have a function definition and formal parameters visible in the Relation Window while you edit the function.
Activate Tracking Group
This group controls when the automatic tracking is activated.
Inside of comments
Select this to have the Relation Window look up symbols when the cursor is inside of comments.
Inside of string constants
Select this to have the Relation Window look up symbols when the cursor is inside of quoted string constants.
Inside all file types
Select this to have the Relation Window look up symbols when the cursor is inside any type of file, not just source code files.
