How to unselect selection in hvplot explorer

Simply following the tutorial, once selecting an axis with my mouse, or multi axes with ctrl or shift, I can’t figure out how to de-select all selections, for example in the groupby part, how do I remove a groupby?

Following the tutorial here: Explorer — hvPlot 0.8.5a1 documentation

Thanks.

I was able to get it stuck once after a multitude of clicks but switching to left ctr key got be back in action again. Generally I’m able to select and multi select then to totally deselect I click one item in the groupby then ctrl click the last highlighted item to fully deselect.

Thanks, Carl.
