In Google drive/docs: Click Insert, Special Character, Latin then find what you need and click on it
In Quizlet.com there are special buttons right on the website.
Another way on a MAC Device (this one will be slower than the codes):
Go to System Preferences (the apple, upper left)
Click on Keyboard
Check the box to "Show Keyboard and Viewers "
Close those windows
In the upper most part of your screen you will see a box with an * inside. Click on this.
Now, click 'show character viewer'
If you need punctuation, click on that.
If you need letters, click on Latin and look for what you need.
Click once on the character you want to add. Exit the windows.
