Is it possible to combine clicks with keyboard events?

I'm trying to test a multi-select component, where if you shift-click on options, you can select multiple options. I've tried this:

```
syn.type(select1.children[0].domNode, "[shift]")
syn.click(select1.children[0].domNode)
syn.type(select1.children[0].domNode, "[shift-up]", function() {
console.log("donezo")
})
```

But it doesn't seem to work. The click happens, but the shift doesn't seem to be incorporated. is it currently possible to do what i'm trying to do?
