I have been having problems in PS where when cloning the blend mode often changes from normal to dissolve on my Windows PC. I have managed to isolate the problem. It occurs if I accidently hit SHIFT + to zoom in when cloning instead of CTRL +. I never realised SHIFT + was an active command. Anyway, I now know what the problem is, but what I want to do is remove/disable the SHIFT + shortcut from the keyboard short cuts. I have looked under EDIT/KEYBOARD SHORT CUTS but I cannot find where the SHIFT + short cut is to remove it or disable it. Nor can I see a search function to help me find it.
I was hoping that was not the case. I regularly hit SHIFT+ instead of CTRL+ when zooming in so I'll have to watch out for this. I recently ruined an image for a competition when the last thing I did was clone out some marks on a road and I didn't notice that the area next to it had slightly dissolved because it was in dissolve mode. Really annoying when I 100% only use Clone in NORMAL mode.
