In Mac, it is possible to use Alt+` (aka backquote, backtick) instead of Alt+Shift+Tab to cycle through open apps.
I tried creating the same mapping using AutoHotKey but failed.
The closest I came to making this work is this
Alt & `::ShiftAltTab
But now when I press Alt+` then Alt+Tab without releasing the Alt key, Alt+Tab cycles backwards as if it were Shift+Alt+Tab.
