Clearing the canvas replaces the entire canvas with the default clear color. You can set this to be any color or change the color each time you clear.

You can define a hotkey to clear the canvas (in the Paint Effects category in the Hotkey editor, define ClearPaintEffectsView). For information on other Paint Effects hotkeys, see Use default Paint Effects hotkeys.
