Question

I want to capture the backspace event, just do the backspace\'s action, then add other action, but I am not sure the backspace\'s original action:Selection. Delete , -1 ?

At last I try use autohotkey to solve this question,some code like down:

     #IfWinActive,ahk_class OpusApp

      ;回车键
      enter::
         send {enter}
         checkStyle()
         return

     backspace::
         send {backspace}
         checkStyle()
         return



     checkStyle(){
    word:=ComObjActive("word.application")
    if(word.Selection.Style.NameLocal="ListItemStyle" and word.Selection.Range.ListFormat.ListString = "")
    {
        word.Selection.Style := "someStyle"
        TrayTip, hint, style chnaged, 3, 17
    }
     }
