 On "ISO" keyboards (as in the two pictures), the í is positioned on the key to the right of the left Shift key.To adapt to 101/102-key keyboards which don’t have that key, the MS Windows QWERTY layout has put the í on the usual key for the 0 (zero) while the 0 has been moved to that key’s AltGr/Option level; On the Mac both layouts (QWERTY and QWERTZ) have this adaptation.A variant of the QWERTZ keyboard has been used in Poland, but QWERTY keyboards have been dominant since the early 1990s.
