Change middle mouse popup to a different shortcut

Is it posable to assign the default.Popup (comand?) to a differnt shortcut? I would like to re-asign tab to the middle mouse popup. I’ve tried doing this in properties under keyboard with no luck. I tried !_default.Popup. I don’t know if it is a command. or if it can be done. Someone let me know if it’s posable.

Thanks.

Yes you can achieve it via re-asign the following macro to the Tab
_PopupToolbar _popup
