How to use a mouse effectively ?
A mouse is a two-button device (sometimes with a wheel between the two buttons or other variations with more buttons) that allows you to point and click commands and options, and drag and drop items on the screen.
Mastering Basic Mouse Moves
To use a mouse effectively, master the following basic mouse moves :
Moving the mouse : Hold the mouse gently with your index finger on the main mouse button (left for righties and right for lefties). Slide the mouse over a clean, smooth surface slowly in the direction you want the onscreen pointer to move. If you run out of room, lift the mouse, move it in the direction opposite of where you need to go, and then set it down and continue sliding the mouse in the direction you want the mouse pointer to go.
Point : Move the tip of the mouse pointer over an object or command. The mouse pointer may change appearance when it’s over an object. If it’s over an object you can click, the pointer may appear as a pointing hand. If it’s over text, it appears as an I-beam, which indicates where the insertion point will be moved if you click the left mouse button.
Rest (Hover) : Rest the tip of the mouse pointer over a menu item to open a sub-menu or over an object to view information about it.
Click : Press and release the left mouse button, typically to select an object or command.
Double-click : Press and release the left mouse button twice in quick succession, typically to execute a command or run a program.
Right-click : Press and release the right mouse button once, typically to open a context-sensitive menu—a menu that contains commands exclusively for this particular object.
Drag : Hold down the left mouse button while moving the mouse. You may drag to move something, draw something, select text, or change the size or shape of an object.
Drag and drop : Click the left mouse button on an object to select it and keep it down while dragging an object from one location to another, and then release the button to drop it in place.
If your mouse has a wheel between the two buttons, you can use the wheel to perform some additional maneuvers.
Scroll : Rotate the wheel forward to scroll down or backward to scroll up.
Pan : Click and hold the wheel while moving the mouse forward or back. (Panning is sort of like scrolling, but smoother.)
Autoscroll : Click the wheel and then move the mouse forward or back. This is sort of like panning, except that you don’t have to hold down the wheel. When you’re done autoscrolling, click the wheel again to disable it.
Zoom in or out : Hold down the Ctrl key while rotating the wheel forward to zoom in or backward to zoom out.
Navigating with a Touchpad
The purpose of a touchpad, a standard feature on mobile PCs, is the same as that of a mouse, but instead of moving the mouse to move the onscreen pointer, you slide your finger across the touchpad.
The touchpad has left and right buttons that correspondto the left and right mouse buttons. However, most touchpads also let you use the touchpad itself to click, double-click, and drag :
Click : Tap the touchpad once to select an object.
Double-click : Tap the touchpad twice in quick succession to execute a command or run a program.
Drag : Tap the touchpad twice, as if you’re double-clicking, but keep your finger on the touchpad the second time down and slide your finger across the touchpad. (This move can be tough to execute.)
