editors/xcoral 3.47_1 MidnightBSD

From the docs:

Xcoral is a multiwindow mouse-based text editor for the X Window System. A built-in browser enables you to navigate through C functions, C++ classes, methods and files. A SMall Ansi C Interpreter (Smac) is also built-in to dynamically extend the editor's possibilities (user functions, key bindings, modes etc). Xcoral provides variable width fonts, menus, scrollbars, buttons, search, regions, kill-buffers, macros and undo. An on-line manual box, with a table of contents and an index, helps you to use and customize the editor. Commands are accessible from menus or key bindings. Xcoral is a direct Xlib client and runs on color/bw X Display.

The example .xcoralrc is in ${PREFIX}/share/xcoral/xcoralrc.fl; cp it to ~/.xcoralrc, and fire up xcoral.
