In Karabiner, how do I set a button to toggle auto-hold that button?

Question

I'm trying the examples in private.xml. I want to do this: When I press control + W, I want it to automatically hold W (until I press control + W again).

And when I do control +left click, I want it to hold left click until I put in the command again. Anyone know how to do this?
