for Morgan and I to be able to do screen captures

That explains why this hidden keystroke also enlarge(zoom in) the first fish on center of the screen in MAT404

very cool, but I dont' see the fish become much more vigorously, or do I have to repeat it many many time in order to see it?

Tiny, since u said this behaviour is amazing, I suppose u notice it on ur own, so how many time did u repeat the keystroke?

edit: Jim answered my question, I see, so it's all become the parameters
