The bottom of your hand should be resting on the desk and should stay on the desk as you move your mouse around. This gives you more control of the mouse.
* The mouse normally has two buttons - a left button and a right button. Today we will only be using the left button.
* A single click of the left mouse button selects an item; it will turn blue. Double clicking (two quick taps) on the left mouse button will open a window.
* Click on the Internet Explorer icon. It will turn blue. Make sure you click on the picture and not the words.
* Now double click on Internet Explorer. The Internet Explorer window will open.
1. Pointing - Sliding the mouse on the mouse pad moves the pointer on the screen. Rest your hand on the mouse, move it slowly around the mouse pad, and see what happens to the arrow on the screen.
2. Clicking - Gently pressing & releasing the left mouse button, while keeping your hand on the mouse, is one way to give the computer a command.
3. Scrolling - Scrolling means moving up and down within a web page or other computer window. This is done by using the mouse to move the "elevator" up and down within the scroll bar at the far right of this screen. You can do this in three ways:
* To move one line at a time, click on the Up Arrowarrow at the top of the scroll bar or the Down Arrowarrow at the bottom.
* To move one screen at a time, click on the empty space within the scroll bar, above or below the elevator.
* To move anywhere within the document, point to the elevator itself. Press and hold down the left mouse button. Now you can slide the elevator up or down by sliding the mouse on the mouse pad. Release the button when you are in the desired location.
