XKeymacs: how to bind to C-S-s?

Question

I'm trying to make XKeymacs translate Ctrl+Shift+s key binding to VisualStudio's File.SaveAll command. But I can't find the correct notation of this key binding.

So far I've tried several options, including the following ones:

• [?\C-\S-s]
• [?\Ctrl-\Shift-s]
• "?\Ctrl-\Shift-s"
• [?\Ctrl+S]
• [?\S-\C-s]

Could you suggest me the right one, please? Or, if you're not familiar XKeymacs, some options I could try to find the right one.

Answer 1

I think [?\Ctrl+S-s] should do the trick.
