RVC Still - remove RVC box from picture?

I am temporarily using only one screen/monitor so if I am using RVC to take a still of the full screen how do I hide the RVC dialogue box so it does not show up on the picture. I believe there is a hotkey for starting a video but is there one for a still?
Obviously using two screens means I just move the RVC box over to screen 2.

There is not a hotkey for a still shot. You would need to have our program minimized in order to take a still shot without it being in the picture.
