Where is the (at sign) on the laptop grand piano?

Alt + 64 = @

Pressing Alt knob, press 6 then 4 and release Alt knob
hold shift and press 2
Shift + 2
press shift and 2.
On a standard QWERTY keyboard the @ sign is located on impossible to tell apart key as the number 2, which is located above the junk mail Q and W.

Now, in direct to access this you will need to press and hold the Shift push button located at the bottom left of the post.

Good Luck!!
