Brushes

I have just started using Krita and am new to digital art the problem I have is when I am using brushes the brush icon changes to a magnifying glass icon and I don’t know how to change it back to a brush .
Regards Ray

Select the Brush Tool from the Tool Box or you can press the B key, :smile:
brush

done that but it doesn’t change any thing

What do you mean? Can you share a screenshot of your whole Krita window?
