Capturing keydown event of MS Word

2019-01-20 17:17发布

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 ?

Sub AddKeyBinding()
    With Application
         ' \\ Do customization in THIS document
        .CustomizationContext = ThisDocument

         ' \\ Add keybinding to this document Shorcut: Backspace
        .KeyBindings.Add KeyCode:=BuildKeyCode(wdKeyBackspace), _
            KeyCategory:=wdKeyCategoryCommand, Command:="TestKeybinding"
    End With
End Sub

 ' \\ Test sub for keybinding
Sub TestKeybinding()
    Selection.Delete , -1 ' I am not sure how to impl the original command
    If Selection.Style = "Some...Style" And Selection.Range.ListFormat.ListString = "" Then
            Selection.Style = "DefaultStyle"
    End If
End Sub

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

It's a little kludgy, but it works:

Public blnCatchBackspace As Boolean

Public Sub CatchBackspace()
    If blnCatchBackspace Then
        ToggleBackspaceCatch 'Remove the backspace key binding
            SendKeys "{BACKSPACE}"
            DoEvents
            'insert code here
        ToggleBackspaceCatch 'Reapply the backspace key binding
    End If
End Sub

Public Sub ToggleBackspaceCatch()
    Dim lngProtection As Long

    With ActiveDocument
        'key binding will error if the document is protected
        'save the current protection state and unprotect the document
        lngProtection = .ProtectionType
        If lngProtection <> wdNoProtection Then .Protect wdNoProtection
    End With

    With Application
        If blnCatchBackspace Then 'clear the key binding
            blnCatchBackspace = False
            FindKey(wdKeyBackspace).Clear
        Else 'apply the key binding
            blnCatchBackspace = True
            .CustomizationContext = ActiveDocument
            .KeyBindings.Add KeyCategory:=wdKeyCategoryMacro, _
                Command:="CatchBackspace", _ 
                KeyCode:=BuildKeyCode(wdKeyBackspace)
        End If
    End With
    'reapply the original document protection
    ActiveDocument.Protect lngProtection
End Sub
