On a Mac, it's Option+n (to get the tilde) and then n or N to place the letter.
Option+e gives you the accent mark and then the next letter you type goes under that accent.
On my phone (which I don't use for DL, but do use to communicate with workers who don't read English), I have to load a Spanish virtual keyboard to get the appropriate diacritical marks. Once you know how, this only takes a second.
And on Android devices, if you hold your finger on the letter for a second or two, it pops up a selection box of alternate characters, which includes accented versions of the letter in question, and other related special characters for other languages (e.g. "a" includes â ä æ etc.).
Alternatively, you can enable an "international'' version of the English keyboard, which lets you easily add accents and other marks with the right alt key. In Windows 10 it's Settings, Time & Language, Language, and then click "English" (assuming that's what you have), then Options, Add a keyboard, United States-International. You cycle through the normal keyboard with Win+Space or Left Alt+Shift. You add an accent either by typing an apostrophe and then the letter (hit space to add a normal apostrophe, or type a non-accented letter next) or holding R-alt with a key. Some characters are hidden under others nearby without accents (for example ä is R-alt+q). You can get ¿¡ the same way.
Except if you address him as "Señor", then you have to use the formal, 2nd person or necesita. And it would be "el Señor" if you were speaking to a third party; or if you were speaking to the man in question you wouldn't put Señor in between the verb and the adverb. Eventually we will learn to hear these distinctions and we won't have to listen five times.
Guillermo8330, Also, Dúo usually accepts "y'all," but not "all of you." If he doesn't, I report it.
It's a fine colloquial contraction for "you all," and those words are elegant enough to be used in very fancy speeches.
God bless you all.
May you all live an amazing life.
You all may enjoy a carriage ride on a warm Spring day at cherry-blossom time.
(BUT! The apostrophe goes after the "y"; trust me on this, y'all!
It's because the apostrophe takes the place of the "ou," when we shorten the word "you.") Southerners started it, but we've spread it all over the country. It just makes a lot of sense to have a plural form of "you." ;^)
I'm a playwright, skeptical. When it comes to dialects, I spell words the way I hear them. I understand the grammatical argument for y'all, but it assumes people are omitting "you" rather than "ya". In my experience, the latter is as common as the former, and hence, "ya'll".
But I do trust you and recognize that you are right if we are talking about words on a page.
