I have a photo of my daughters now deceased dog. In the picture one of the dog's front legs has been shaved bare. My daughter asked me for a print of the photo with hair on the bad leg. I assumed that "healing brush" from the side bar would be the thing to use. I clicked on healing brush and a box in the upper right said to depress Cntrl Alt which I did. The circle on the screen changed from round to cross hair with no further instruction. I went to HELP, typed in healing brush and nothing was found. I found nothing in tutorials about the healing brush. Is this a working feature of just an icon to fill in empty space? I'm a beginner but I'm beginning to think I bought a less than great piece of software. Maybe the healing brush function wasn't the right choice? Any help is appreciated.
