Double Click

When using brushes that permit multiple clicks, such as the Metaball brush, a double-click is often needed to confirm an action. I clicked once at each blue mark and twice at the green mark.

Triple click

When using certain brushes, such as the Coat brush, you may need to click three times in the same spot. Here I clicked once at the blue marks, twice at the green marks, and thrice at the red mark.
