Changing monitor layout

Hi,

I have a question. I use VMWare Workstation 12 on a 3-monitor machine. I want to use different monitor layouts for my VM (i.e. have the VM show on two of my three screens.) VMWare Workstation 12 has a handy button for this, but my problem is that I only use the computer using the keyboard, not with the mouse. I can't figure out how to change VM monitor layout using the keyboard. How do I do that?

Thanks,

Ram.
