How many times have you drawn a Freehand Callout and realized it wasn’t exactly the shape you wanted, so you deleted it and started over?
Well, did you know you can modify the shape of your Freehand Callouts by pressing the Option key?
With a FreeHand Callout selected on your clip, press Option and you’ll see your ‘plus-shaped’ mouse cursor will change to include a little minus sign in the lower right corner. (If you’re using the freehand draw option, you won’t see any change to your cursor.) Now, when you click and drag on your existing Freehand Callout shape, you will subtract from the image, rather than add to it.
This works for both the box and the freehand drawing Freehand Callout options.
