Indeed it does! (Well, the latter suggestion does.)

I did this:

highlight macro_skin guibg=bg guifg=DarkGreen gui=bold ctermfg=022 cterm=bold
match macro_skin /\%(\<c\)\@<=\(mount\|umount\|open\|close\)/

And that's it. (And just a few minutes after posting, to boot!)

Just a detail: is it possible to enumerate the keywords in a separate
declaration, to improve maintainability? (The actual list is more
extense). I'm thinking of something similar to:

syntax keyword Foo open close mount umount

Even if it's not possible, this is good enough.

Thanks

Jorge
