If you work for long hours on a computer, you might be concerned about wrist injuries that can occur as a result of continually using a mouse. There are some alternatives available that can give your wrist a rest while still letting you use your Mac computer efficiently.
Use Keyboard Shortcuts
There are several ways you can use a keyboard to replace a mouse. You can set keyboard shortcuts for menu items using the options on the Mouse & Keyboard pane in the Mac OS X System Preferences. You can have even more options for setting keyboard shortcuts for launching applications and using menu commands with a Microsoft or Logitechkeyboard and the software provided by those two companies.
Use Speech Recognition
Mac OS X comes with an advanced speech recognition feature that lets you give commands using your voice and a microphone. Note that speech recognition is not working in Mac OS X 10.6.2.
Use a Graphics Tablet
If you own a graphics tablet, you can use the pen that comes with the tablet to replace your mouse. Once the tablet is connected to your Mac, you should be able to use the pen to select and move objects on your screen. If you own a Wacom tablet and install the Wacom software, you can set the tablet's pen to function in ways similar to a mouse.
Use Universal Access
Mac OS X System Preferences has a special option on the Universal Access preferences pane that lets you use the numeric keypad on your keyboard in place of a mouse. Once you activate Mouse Keys, you can use the numeric keypad to move the mouse pointer up, down, left, right, and diagonally. You can even use the keypad to replace mouse clicks.
