I am trying to edit a line of code within a program that I use for work.

I need to use the insert key to be able to add additional spaces that I can then type letters, numbers or characters.

How to get this function to work on my MacBook Air?

    What program are you using on your MBA that requires an insert key? In that program are you certain that the Insert key will do what you expect on your MBA? Try plugging in a PC-style USB keyboard and pressing Insert in the program; does it work as expected?

I need the insert key in the Midnight Commander (MC) running in Terminal and in Remote Desktop Connection (RDP) when connecting to my Windows PC.

For Midnight Commander the answer is Ctrl+T.

For RDP I did not find better solution than to use a free program on Windows AutoHotkey and map the key to chosen key combination, for instance this macro maps the Insert key to Ctrl+Alt+I :


Answer found on Microsoft forum


FN + Return = Insert

(MacBook Air 13)

Also Works on MacBook Pro.

It depends on the physical keyboard and on the keyboard layout. You can try...

ctrl+fn+M OR ctrl+fn+

  • Finally, something that worked. CTRL+FN+M worked on my MacBook Pro (4,1). Everything else failed.

I posted a possible answer to this question in a similar question topic on StackExchange:

How do I simulate the Insert key in Windows on a MacBook Pro?

In it, I'm explaining how to re-map the key combination Fn+Ctrl to Insert using Karabiner.


On the latest Macbook Air 13" ctrl+ works.

  • "Latest" changes over time. It would have been better to explicitly say the model/version in your answer. For instance, in the "latest" MacBook Pro (with Apple M3 Pro) running the "latest" Mac OS X Sonoma 14.5, this combination doesn't work. Commented Jul 8 at 13:31
