> Adding Freehand Callouts to Images
> You can highlight freehand areas directly on images, using either a circular paint brush or a rectangle tool. You can use freehand callouts to blur out sensitive data or create a highlighted box around the content you are discussing, for example.
> To create a freehand callout, follow these steps:

> 1. | Set the location of the scrubber.

> 2. | Select an image on your canvas.

> 3. | Click the Callout Properties tab, click the + Action button, and click Freehand. (Because you’re working on an image, Freehand is the only callout option.)

> 4. | When ScreenFlow displays the tool palette in the upper right corner of the canvas, select either the brush or the rectangle tool. If you select the brush, you can set the size of the brush.

> 5. | Draw the highlighted region on your selected image using your mouse. To brush-on a highlighted area, select the brush tool, set the brush size, then click and drag the mouse to define an area. To create a rectangle highlighted area, select the rectangle tool, then click and drag the mouse to define an area

> 6. | Use the callout properties to adjust the look of your callout.

> 7. | To remove a brushed-on freehand callout, select the brush tool, then hold down the Option key and the left mouse button while moving the mouse over the highlighted area to erase it. To remove a rectangle freehand callout, select the rectangle tool, then hold down the Option key and the left mouse button while moving the mouse over the highlighted area to select it. When you release the mouse button, the callout is removed.
