Keyboard clicking with a mouse

I've been lurking for a while now, and thought it time to ask my first question here. In a while, I'll even be able to give my first answer ;)

I would like to simulate a keypress with a macro. I can use /click to simulate a keypress on an actionbar. This can be used for macrobranching and other nice gimmicks (http://www.wowwiki.com/Making_a_macr..._with_.2Fclick). But it might also be possible to use it to simulate a keypress on my keyboard. Doing that would allow me to use my mouse to click an actionbar button, which would still activate my faithfull servants.
/cast holy shield
/click "ctrl-B"
This should activate my holy shield, and press ctrl-B. This simulated keypress would be picked up by KeyClone which would make my servants do something naughty. But I'm not sure if this is possible, and I can't find the synthax if it is. Any thoughts?
