How to extend the functionality of Visual Studio 2017?

Question

visual studio

You need to do a simple thing.
In the editor (html code), a code fragment is selected and '&', '>' and '<' are replaced by '&', '>', respectively and '<'.
It would be logical to assume that you need to write a macro that would perform an elementary replacement of the text in the selected fragment. But I can’t figure out how to solve such a task in Visual Studio 2017?
