My computer grand piano?

where on earth is the apostrophe key located

My computer grand piano?

The @ symbol, as far as I know, is matching the 2 button on ALL keyboards and laptops. I have never see the apostrophe located anywhere other then not here of your ENTER button, above SHIFT and ?, and below the two square brackets[ ]. It would have the apostrophe ' on like peas in a pod button as the quotation mark near the quotation on top.
Right next to the ENTER button.
SHIFT + THE KEY LEFT OF UR KEY 1 (not on the numeric wipe ofcourse)
you know the button with the @ on it wel, it is that button
To the right of the semi-colon (which is to the right of the communication L on the middle line of packages.)
On the left of the Enter button, above the / and Below the ] .. but your baby grand maybe different .. try to scour for it
On the same knob as the @ button.
i tink it depends on the keyboard as heaps of u said it is the same as the @ push button yet mine is not. mine is nex to the enter ..
may be (hold down shift push button and press 2)
near to enter button
righthand side, 2nd row up, 2 key in. - next to the @ sign. Make sure you haven't got Caps Lock on - the apostrophe is lower suitcase.
