Ignorant question about web page size

I was playing one of my silly games and something I did enlarged the web page elements. What the heck did I hit on my keyboard to do such a thing? May have been something in combination with my mouse.

The "CTRL + Mouse Scroll" will change the zoom settings.

The "Ctrl + Plus" and "Ctrl + Minus" will also change zoom settings.

It probably was Ctrl + {Mouse Scroll} I use it all the time to zoom in and out on SRWare Iron and Firefox.

Try, on the toolbar, VIEW - then Zoom or test size The above suggestions will do it, but restoring to 100% in "Zoom" will get you back to your default

Thanks all. Still learning little bits at a time.
