Against automatic entry of dia-critical marks, again.
So a new OS comes along, Yosemite, and the irritating auto “correcting” of words is, again, re-installed (See this previous comment). But this time I find that Apple allows us to switch it off, and it is actually switched off, too!
1. Open System Preferences from the Apple menu as usual, then go to “Keyboard”
2. Choose the “Text” tab
3. Uncheck the box next to “Correct spelling automatically”
PS. Not. My joy was premature. The above did not work at all!! However, resorting to the suggestions in my previous comment did the job! (date: 14-05-2015)
