Expanding tool panels

Hi,

On the right of the MoI interface, you have the Draw Curve / Draw Solid and other tool panels. Be default some of these are minimised to save space. However, on larger monitors they can all be expanded. I just can't remember how to do this. Can some one remind me, please?

Thanks
Mark
