Style brush pickup keyboard shortcut?

I know that ‘w’ is the keyboard shortcut for the style brush. Holding down ‘w’, the first time i click an object, the brush sucks up the style, then, for all subsequent clicks on other objects, the brush paints out the same style. Great; but is there a keyboard shortcut for clearing out the brush? I have to go click the style-brush iconlet at the top of the window frame and scroll down a menu to get the ‘clear contents’ item. That much mousing & clicking disrupts workflow. Is there a keyboard solution, please & thanks?

I FOUND IT – it’s ‘ESC’
