You may not use accent marks a whole lot, but for when you do, knowing how easy it is to use them on the Mac comes in handy.
There are a couple different ways to implement accents on the Mac:
If you hold down the option key while hitting the letter, the mac will guess which accent (if there are any) you’re wanting to use, you can then type the letter again without the option key to insert it below the accent mark.
Another option is to just hold down the key of the letter you’re typing. The Mac OS will pop up a list of accent choices (if there are any for that letter) and you can use the number keys or your mouse to select the appropriate accent mark.
