Equivalent of INS key: no key combination whatsoever works on my MacBook I have a MacBookPro 2011 (Italy) with OS X 10.11.6 and I'm looking for the combination that works just like the INS key found on Windows to overwrite text while I’m typing. The INS key is not found in the built-in keyboard, so I think there must be some other way to toggle this function!

To avoid any misunderstanding, you can see the keys found in the Italian built-in keyboard in the picture here:


I tried so many combinations, but none of these works:


FnEnter⏎ (it just produces a new line)
FnM (it just types an "m")
FnI
ControlT


And many more (for instance some combinations mentioned here: How do I simulate the Insert key in Windows on a MacBook Pro?)

Do you have any suggestions? This is driving me crazy, any help would be much appreciated, thanks!
If your purpose is simply to have the overwrite feature in Word for Mac or its free clones, then you can activate it inside the app and go to Tools > Customize Keyboard >  Commands and select "Overtype" and set whatever keyboard shortcut you want for it.
