Formatting is best handled through the appropriate use of Styles, not by overriding an existing Style's formatting with something else. So, if you want some selected text to have "the formatting of a heading, or title", the appropriate way would be to apply the relevant Style to the selection. No macros required. Yes, you could use a macro to apply a Style to a selection, but that seems overkill. Regardless, the macro would not "copy a property or properties from one element in a doc and apply it to the currently selected element" in the sense you envisaged.
