Known issue. In fact, someone already started work on this:

QKeySequence isn't available as a type to QML. Did you mean a string
property for key, which would be converted to a QKeySequence?

It wasn't explained well in the Actions API thread, but the thought
was that this could be initially exposed with the Actions API. The
string shortcut property there would be registered as an application
global shortcut, so you could use Actions separate from any menus to
do this. What do you think of having it just in the action API, or do
you think it needs its own item?

I agree that functionality would be nice to see for shortcuts in Qt.
But it's probably a separate issue, distinct from exposing the current
functionality to QML (which is a logical first step).
