i just don't know how to put the accents on the letters

On your PC computer,

enable the [num lock] key so you can use the number pad on the right of your keyboard,

alt + 138    Press the numbers 138 while holding down the alt key to produce the accented "e" (è)

alt + 133   Press  the numbers 133 while holding down the alt key to produce the accented "a" (à)

alt + 149   Press  the numbers 149 while holding down the alt key to produce the accented "o" (ò)

Ask me anything
