The button should directly call the Windows Copilot helper. But recent tests have shown there’s no magic here.
Pressing the Copilot button turns out to be a cleverly disguised combination of three keys: Left Shift + Left Windows + F23:
This is odd because most modern keyboards only have 12 function keys (F1 – F12). The thing is that there were keyboards with additional function keys (F13 – F24), and Microsoft seems to have decided to use the unused F23.
Tom’s Hardware journalists uncovered this detail by testing the button on a Dell laptop and using a special program to monitor keystrokes.
So we couldn’t get a new button; it’s just a handy shortcut to the old combination.
