where is the# key on the lenovo

Solution
If you're using a European keyboard it should be on top of the 3 key - use SHIFT + 3.

Update: On French keyboards it's still the 3 key, but you may have to use ALTGr + 3.

over number 3 key so Shift 3 and you should get #. that is if your top row of keys are spelling QWERTY under the numbers if it spells AZERTY then its somewhere else
