In OS X Yosemite, every time I type two dashes in a row, or — or ———, it automatically converts it to a long dash, or EM Dash.
How do I change this auto correct?
In older versions of OS X (Mavericks), all you had to do was go to the Keyboard preferences (System Preferences, Keyboard icon), under the Text tab, and add your own Replacements (replace — with —) and it would do that replacement instead – essentially replacing one with the same.
This was a simple workaround.
However in OS X Yosemite, the Substitutions feature seems to have taken over…
Now in each application where this occurs, simply go to the Edit menu, and select Substitutions, and then uncheck the Smart Dashes item.
