Lightroom circles

As I use clone, heal, or adjustment brush, each leaves a sized circle at it's work point, which can be resized or moved around, but they remain.
My question (I'm new to LR): The circles remain as I do more work, and become a nuisence. Keyboard N will hide them, but how can I remove their appearance completely (without exiting LR).
Thanks

H will hide them, or you can delete them by selecting it and pressing the delete key on your keyboard.

Once you have completed your cloning or brushing, close the tool by clicking 'Close' on the panel or the tool icon. The panel will close and the circles will disappear but the effect will remain, unless by mistake you click 'Reset' instead of 'Close'. If at a later time you want to do more cloning or to change the previous brush work or clones, open the panel again and select either 'New' or 'Edit' for the brush or simply click on the cloning circle.

Thanks, deleting the circles while maintaining the effect was what I wanted.
