Dogs don't use computers, because it is difficult to "mark" every website they visit.

What did we ever do before mouses?Have you ever noticed when you move the mouse pointer around the screen of your computer, sometimes the pointer changes from an arrow to a double ended arrow? This is when you have the very tip of the pointer on the top or bottom edges of the window you are working with. When the arrow is double ended, you can hold your left mouse button down and drag the screen in our out, up or down, to make it bigger or smaller. When you let go of the mouse button, the window will be a new size. If you slowly move the mouse pointer around the corner areas of the window, you will see diagonal arrow pointers. Hold the left mouse button down, and move two sides at the same time! What did we do before mouses??
Got questions?
