How can we write alt code without the num lock key?

[davidko]

Hi,

I own a X230 and I am very satisfied.

However, I need to type symbol frequently. I usually use ALT+ numerical code of the symbol on my desktop.

for laptop there is usually a NUM LOCK key to activate this function but the X230 lacks this key.

Hence my question: how can I enter ALT+ code to quickly type symbols?

Thanks

David
