I have tried a few of these but none seem to work. Why is it working for some people and not me ? I am using CHROME, if that helps.
Ah...seen my mistake...apparently you need to activate the Number Lock !
Lets try again 12
No...doesn't work either !
Lets try FN, Alt and then 253, but using the K,I, and L keys
12²
Got it at last ! ...I am terribly relieved....thanks everybody !
