The Smudge tool evokes finger painting. It works in two ways:

If the Flow option is set to 0.00 (default), the Smudge tool uses the current brush to smudge colors on the active layer or a selection. It takes color in passing and uses it to mix it to the next colors it meets.
When the Flow option is more than 0.00, the Smudge tool works as a brush using the foreground color of the toolbox and blend it with the underlying color.

3.16.1. Ativando a ferramenta

Existem várias formas para ativar a ferramenta:

From the main menu: Tools → Paint Tools → Smudge.
By clicking the tool icon in the Toolbox.
By pressing the S keyboard shortcut.

3.16.2. Teclas modificadoras (por padrão)

Shift: The Shift key places the smudge tool into straight line mode. Holding Shift while clicking the mouse Left Button will smudge in a straight line. Consecutive clicks will continue smudging in straight lines that originate from the end of the last line.

Shift click and drag to create line
Ctrl: Pressionar Ctrl com o Shift, faz com que o ângulo entre duas linhas sucessivas variem em etapas de 15°.

3.16.3. Opções

Figura 14.81. Smudge Options

Normally, tool options are displayed in a window attached under the Toolbox as soon as you activate a tool. If they are not, you can access them from the main menu through Windows → Dockable Windows → Tool Options which opens the option window of the selected tool.

Opacidade, Pincel, Tamanho, Aspect ratio, Ângulo, Espaçamento, Dureza, Força, Dinâmicas, Opções de dinâmicas, Aplicar espalhamento, Smooth stroke, Lock brush to view, Expand Layers

Hard edge: this option gives a hard contour to the smudged area.

No erasing effect

If smudging will decrease alpha of some pixels; this alpha is not decreased if this option is checked, and so pixels are not erased. This is useful to fill a gap between two color areas.

Usar amostra combinada

If you enable this option, the effect is not calculated only from the values of the active layer, but from all visible layers.

See Seção 3.12, “Clonagem” for using Sample Merged in non-destructive image editing.

Taxa

This option could be called "Smudge length" since it sets the length of the smudging effect in a stroke.

1: Rate=20 2: Rate=60 3: Rate=90

Fluxo

We already saw the different behavior of the “Flow” option when it is set to 0.00 (works as the original Smudge tool) and set to more than 0.00 (uses the foreground color for smudging).

Here are comments and examples for the “No erasing effect” and “Flow” options from gimp-forum.net:
