How can off-the-shelf editors be reused in applications that need mature editing support? We describe our editor multiplexer which enables interactive, application guided editing sessions using e.g. GNU Emacs and Vim. At a cost of less than 1 KLOC of editor specific glue code, both IDE builders and users benefit. Rapid integration of existing editors reduces application development cost, and users are not confronted with yet another foreign editor with its own learning curve
