+# Quickly Type En Dashes And Em Dashes
+
+To type a hyphen, you hit the key right next to the zero: `-`. But what about
+if you need the similar looking en dash and em dash?
+
+Some programs have text areas that will automatically convert two consecutive
+dashes into an em dash.
+
+There is a more reliable method that can get you both: these two keybindings
+which are a variation of the `-` key itself.
+
+* `Option -` will produce an en dash (–), named that because it is typically
+  the width of the n character.
+
+* `Option Shift -` will produce an em dash (—), named that because it is
+  typically the width of the m character.
+
+The en dash seems to be the less familiar of the two. For more details on when
+to use that, [check out this excerpt from Dreyer's
+English](https://twitter.com/jbrancha/status/1344345683294380035).
