Are you Italian or Spanish or French working in a foreign country with an English keyboard ? Watch out your accents !
In Italian, é and è are both used and mixing them up is a mistake.
In Spanish, ñ cannot be replaced with a n, año and ano have different meaning (don’t confuse them) 😀
Your keyboard won’t have the accents you need, but you can press and hold the left ALT key while using the numeric pad to insert the symbols/letters you need
ALT + 164 = ñ (tengo 30 años)
ALT + 138 = è (italian verb. la casa è verde)
ALT + 141 = ì (Forlì is an italian City)
ALT + 130 = é (with an English extended keyboard, you can write it with right ALT + e as well)
ALT + 160 = á
