I recently had to look up how to disable Smart Quotes in Google Drive.
I found the solution after a few seconds googling1.
Just thought I'd paste it in here, in case I cannot find it again.
Option 1
Disable Smart Quotes by clicking on "Tools" -> "Preferences -> turn off "Smart quotes".
Option 2
Leave Smart Quotes enabled. For straight quotes, immediately press Ctrl+Z to Undo the AutoFormat.
The post had some additional info on how to enter smart quotes, even though smart quotes was disabled, but that didn't work for me, and I didn't need it.
