Templates - Finding Field Codes

When editing templates, I know how to find field code I need by putting my cursor in the appropriate field & seeing the code on the bottom left corner. But how do I do the reverse?
Meaning, I’m editing a template and see the field code, but how do I find where that field code is in TaxCycle?

Copy the field code from the template and paste it into the F4 Fast Find box when you have an open return. It should then take you to the field.
