Daca mouse-ul will leave it difficult, and at that moment you don't have the possibility to get one quickly another new one, then it would be very helpful for you to know that keyboard (more accurate numerical keys) can replace functions "deceased". :)

To activate mouse-keyboard (or tastatura-mouse :P), you have to make some small changes in Control Panel.

Enter Ease of Access (Control Panel option) and click on Change how your mouse works.

In the displayed window locate Control the mouse with the keyboard And check the option Turn on Mouse Keys.

Data Apply and OK and continue your work. :)

cursor you can move it with the keys 1,2,3,4,6,7,8 and 9, key 5 being a substitute for Click-left. The role of double-click the key will have it + (plus).

O shortcut to make these changes faster would be the key combination Alt+Shift+NumLock.

After these changes you can activa or disable keyboard-mouse by pressing the key NumLock. Have fun! :D
