Most computer users are comfortable and possibly more productive when they have skills to use both a mouse and keyboard to navigate through their computer. But unfortunately the truth is that most users find it somewhat difficult to switch to another input device when their favourite one stops working.
For example, if your mouse stops working when you in the middle of something important, your only option is to find a replacement mouse fast or use the keyboard.
When you find yourself in this situation there is no need to panic. If you have ease of access settings ready to use, you only need to hit a keyboard shortcut in order to activate an option to move your cursor by using the keyboard instead of the mouse.
