Four Latin layouts join: Spanish (Spain and Latin America; n-tilde on the
home row, the period beside space with the inverted marks), Portuguese,
Italian and Polish, each holding its accented letters under the keys.

Holding a key with several characters under it now raises a strip on
the row above (beside the key on the top row, always towards the side
with room). Lift without moving for the first - the digit or symbol the
key always held - or slide along the strip and lift on the one you want.
Keys with one character under them type it at once, as before.
