Ditch, VC for sma files, and get a copy of this:

I bought my copy -really no kidding- at least 6-7 years ago.
Great editor. Been using it for most everything except directly hacking MS MFC apps, then I use VS.
If you go to configuration/ syntax highlighting then open the file that controls the highlighting, you can setup any file any way you want to including specifying individual keywords if you want to.
GREAT editor.
1) Get a copy
2) Send the Brit the bucks.
3) It is worth it….
