Apple - What leads to Windows thinking I pressed the Insert key on a MacBook Pro?

Apparently, for Windows running natively on Apple hardware fn + return creates an Insert key press.

While running Midnight commander in terminal on MBP (OSX Yosemite) I use ctrl-T for simuating INS

I have been able to find no way to do so, with a modern Macbook Pro. (The keyboard view only shows a minimal keyboard)

Apparently fn + return is the winner.

Not on newer Macs, that key combination is just 'enter' (instead of 'return').
