Yes sure. I was rather suggesting to OP that there's no need to wait for the developers to create a shortcut, you can hand-roll your own; though naturally you have to check out conflicts with what exists as a system shortcut.

My favourite App for this is Nisus Writer Pro, as it has its own shortcut creation system in which you can create multi-character shortcuts, as well as using the range of modifier keys. So I have it set that red text is invoked with Cmd-RR and black with Cmd-BB and so on ... brilliant..
