This moves the cursor forward to the next highlighted reference.
To enable reference highlights, select Options > File Type Options , and check the box that says "Highlight references to selected symbol". This option is set per-file type.
When enabled, Source Insight highlights all references to the symbol at the cursor position. For example, you can click in a variable name, and all references to the variable will be highlighted. The references are context sensitive, so a symbol in a different scope will not get highlighted. The highlight will only appear if more than one instance appears in the file.
