Do any wireframing tools support keyboard control for accessibility testing?

I have some keyboard interactions that I want to test, namely the use of a new sortable card component that I want to make keyboard accessible. The problem is that I use Balsamiq and there is no way of simulating what should happen when a keyboard user tabs through the controls to the card stack. Are there any wireframing tools that can simulate the act of tabbing through controls? I'm at the point where I think I may need to build the interface in HTML to just simulate the interactions!
