To change the blend mode of the mask before it is drawn, choose an item from the Mask

Continue drawing around the layer you are masking. To close the mask, finish the line at the
mask’s starting point. A small circle appears when the pointer is over the starting point.
Note: If you don’t close the mask at its starting point, the mask is closed when you release the
mouse button.
A small circle indicates
target to close mask.
The mask is completed.
