How to type option + insert
My understanding is on Macs it will depend on the keyboard type. The different options I am aware of are:


Do a fn + return keyboard shortcut
Do a fn + control + return keyboard shortcut
Press the help key


I do not know if any of these work on a 2016 MacBook Pro keyboard. I suppose you would have to try holding the option key as well as the above options to see if any work.
