Not really. As ever, it depends what you want to do. Some places that might get you into the code are the more functionally restricted areas, say menu.c to see how the menus are built (you can then use the same techniques to adapt them yourself), and macros.c, many of whose functions are the embodiment of the built-ins described in the macro subroutines help, so it's easy to understand what's happening. Again, modifying or adding macro built-ins teaches you about the macro data structure (DataValue) and how that's manipulated. The actual language is implemented in parse.y (which describes how the language is compiled to instructions) and interpret.c (which implements those instructions and the execution machine). More complicated, and X/Motif specific, are the main files nedit.[ch] and windows.[ch]. If you want to add more properties to NEdit's windows, you'll be playing with these, in particular adjusting the WindowInfo structure. Opening and closing files is managed in file.c. The actual text manipulation is handled in textBuf.c and its display by the widget textDisp.c and text.c. X resource preferences and the nedit.rc read/write are handled in preferences.c, regex stuff in refexConvert.c and regularExp.c, highlighting in highlight.c, searching in search.c and so on. As you can see the file names are a guide. NEdit is generally well commented so, although it's often hard to see the wood for the trees, you shouldn't be too led astray by reading them.
