If you are referring to , for instance the number 1 next to the letter J, I have them; they are blue on my keyboard.
but in MS words 2016, If I wana write a é, and do the ctl alt 1,3,0 with the blue numbers ( the normal white number on top won't do anything ) there a popup window showing up and it doesn't work...
so for web it's clt alt 1,3,0 blue,, and for ms words it's alt x like you said , or in world, insert, symbol, special caracters...
your link was a winner
thanks again man
