Have a need to hide the toolbar yet still need to crop an image. Is there a keyboard command that would allow me to crop with the toolbar minimized? Guidance sought

hi bro!
look at the right bottom of Paint ;) & change the look from 100% to what you like.
a better solution is to use an advanced software like photoshop or corel draw
good luck

I agree. Just be careful. I have made many mistakes with MS Paint.
