You’re nearing deadline and got important stuff to complete; your mouse stops working! You’re not sure what’s the problem, neither time to trace the problem. What can you do? Well, first of all, relax, there is always a plan B. 🙂 You’re going to control your Mouse cursor using the Keyboard.
Start by pressing Left ALT + Left SHIFT + Num Lock on your keyboard. If nothing happens, try to press and hold both the left ALT and left Shift keys, and hit the NumLock key. This should open a small box, asking if you want to turn on Mouse Keys.
Note: After you enable the Mouse Keys, an icon should be displayed in the system tray. Use it to increase/decrease the speed of the mouse cursor by clicking Settings. I recommend you to check the box that makes the mouse move faster while the Control key is held down and maximize both sensitivity settings – otherwise, the cursor moves painfully slow.
