How it works
Quotation marks show the words someone says out loud. One mark goes before the words and one goes after, the way two hands hold a cup.
Round brackets hold a little extra bit: take it out, and the sentence still works.
Marks and brackets come in pairs, so if you open one, always close it.
The quotation mark is shift and the apostrophe key. Round brackets are shift and nine to open, then shift and zero to close; the keys are on the right, so hold the left shift.
