The Awesome AutoHotkey Fix

Now that we know the shortcut key that actually works in Windows 7, we can use a small script to make it work the way we really want it to. With AutoHotkey installed, create a new script with New –> AutoHotkey Script, and then paste in the following:

#IfWinActive, ahk_class CabinetWClass Backspace::    ControlGet renamestatus,Visible,,Edit1,A    ControlGetFocus focussed, A   
if(renamestatus!=1&&(focussed=”DirectUIHWND3″||focussed=SysTreeView321))
{
    SendInput {Alt Down}{Up}{Alt Up}   }else{
      Send {Backspace}   }
#IfWinActive
