Yes they are in a cluster; k, i, l, o.
I have removed the keypad but the 2 piece bits unde neath also came away on all the keys! How do they go back together? Is it worth trying if the keys do not work when pressing the button underneath the keypad? I have tried the Apple recommended method (Via PREFERENCES) of seeing if they work, but they do not. Looks like £129 to be spent on a new one!
