Well a good program editor - like mvDeveloper (grin) or Doug's U2 Editor -
does a lot more than just highlight. 

It's about ease of navigation and assisting developers to work faster and
more efficiently. Doug and I have taken different routes to that - Doug's
editor is arguably more powerful, mine is arguably lighter - but where they
both score over general editors is in understanding the code they are
dealing with.

That manifests in all kinds of ways. In mvDeveloper, for example, you can
right click to open a called subroutine or include file, can jump to a label
in a program, can quickly navigate a program by label (Ctl-U move to
previous label, Ctl-D down to the next label), can comment in and out (even
for PROC), can perform a quick conversion on an internal date and time, can
edit associated multivalues in a grid, pull up keyword help .. 

In short, lots of things that are specific to the platform and to the people
who use it.
