A hyphen goes between words or syllables to link them together.
Example: Editors appreciate dash-savvy writers.
All English keyboards: the hyphen is the minus key next to zero.
en dash (–)
An en dash denotes a range between numbers or dates. It is so called because it is the same length as the letter “n.”
Example: The author used multiple dashes on pages 4–90.
Microsoft: alt + 0150
MS Word auto-format: enter [space], [hyphen], [space] between words.
Like this: word – word
Apple: option + hyphen
Smartphone or tablet: hold down the hyphen key until more options appear. The N-dash is probably the middle choice.
em dash (—)
An em dash denotes an interruption. It is so called because it is the same length as the letter “m.”
Example: Authors—even professional ones—often use dashes incorrectly.
Microsoft: alt + 0151
MS Word auto-format: enter [hyphen][hyphen] between words without spaces.
Like this: word–word
Apple: shift + option + hyphen
Smartphone or tablet: hold down the hyphen key until more options appear. The M-dash is the widest choice.
