AutoHotkey send {Del} not work in explorer on Win10

Question

I want to use Alt+d to trigger Delete.

!d::Send, {delete}

This works almost everywhere except in explorer. Nothing happens when select a file and press Alt+d. Why is that?

Environment: latest AutoHotKey, Windows 10-64bit

Answer 1

Try

!d::
    IfWinActive ahk_class CabinetWClass ; explorer
    {
        ; The control retrieved by this command is the one that has keyboard focus
        ControlGetFocus, FocusedControl, A  ; A means the active window
        ; MsgBox %FocusedControl%
        If FocusedControl contains DirectUIHWND,SysListView
             SendInput, {AppsKey}d
        else
            Send, {delete}
    }
    else
        Send, {delete}
return
