Lessons learned and answers pending

My cat just taught me a lesson on how to operate my computer. Some time ago I visited a website on a somewhat regular basis. One day the resolution of that one site went all wonky on me. To this day the resolution of that one page is still odd. I have never been able to determine what happened to it. Today the cat stepped on my computer and the page I was on exploded. It was almost completely impossible read due to the stupid size issues. Every other page retained original size. There were only two possible conclusions that could be drawn from this. Either there is a keyboard command of which I am not aware, or my cat is magic. Upon observation of the cat who was occupied cleaning his bum, I concluded that there must be a keyboard command. After several minutes attempting to locate the general region of the keyboard stepped on and further attempting to deduce any possible key combinations, I found the solution. To confirm, I reset that first page back to its original size, then rested content in the knowledge that I am not a complete failure. Also, where do cats keep their bones when they are not using them?
