MAC — em dash
On Macs, you can use the Shift-Option-Hyphen to insert the em dash.
There are other two ways to add em dash in Google docs/ drawings (source):
(1) replace consecutive hyphens
Using two consecutive hyphens is the next best alternative on keyboards without a dedicated em dash key. But, you can also configure Google Docs to automatically substitute two hyphens with an em dash whenever you insert them.
Now, add the em dash into the box under with Shift-Option-Hyphen (on Mac) keyboard shortcuts. Or, you can choose to copy and paste the em dash character here: —
Click OK to add the substitution to Google Docs.
That’s it. You should now see an em dash whenever you press the hyphen key twice and follow it up with a space.
(2) insert as special character
There’s also another way to insert an em dash in Google Docs/Drawings, and that’s via the Special Characters selections screen.
