I have a VSTO application as an add-in to MS Word and I want to set keyboard shortcuts to the ribbon buttons

Question

When I developed this app (in C# Visual Studio 2008) I asked the same question (actually managed to find an answer on the MS forum, for which I deserve a prize of some sort)

Answer 1

Its too late to answer but worth sharing.

I have used Keyboard shortcuts in my project. Basically this shortcut key should bring a WPF form called SignOff. This WPF form can be displayed either by clicking a button in from the ribbon tab or by using keyboard shortcut(Ctrl+ Shift +S).

There are four places where I need to write my code.

1. The action method for the ribbon button called on click event.

   public void btnInsertSignoff_Click(IRibbonControl control) 
   {
     InsertSignoff();//This method displays the sign off form 
   }
   

2. The following code binds a key board shortcut with VBA code in the Addin Startup / Document Change event

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
     Globals.ThisAddIn.Application.KeyBindings.Add(WdKeyCategory.wdKeyCategoryCommand,    "InsertSignOff ", Globals.ThisAddIn.Application.BuildKeyCode(WdKey.wdKeyControl,   WdKey.wdKeyShift, WdKey. wdKeyS));
    }
   

This link shows how to call VBA Code using Keyboard shortcuts. http://www.wordbanter.com/showthread.php?t=31813

I followed this example but instead of VBA I did that in VSTO Addin Startup event but the second parameter " InsertSignOff " is a VBA method in step 4.

3. Wrote another method called InsertSignOff (Following exposing VSTO method to VBA).

   [ComVisible(true)]
   public interface IAddInAdapter 
   {
      void InsertSignOff ();
   }
   
   
   [ComVisible(true)]
   [ClassInterface(ClassInterfaceType.None)]
   public class AddinAdapter : IAddInAdapter
   {
      public void InsertSignOff()
      {
         InsertSignoff();//This method displays the sign off form
      }
   }
   

This link explains how to expose VSTO code to VBA http://msdn.microsoft.com/en-us/library/bb608604.aspx

4. Created a .dotm file in the user templates location “C:\Users\\AppData\Roaming\Microsoft\Templates” which contains the following VBA code

   Sub InsertSignOff ()
       Dim addIn As COMAddIn
       Dim automationObject As Object
       Set addIn = Application.COMAddIns("Wordaddin.AddinAdapter")
       Set automationObject = addIn.Object
       automationObject.InsertSignOff  
   End Sub
   

Hope this helps some one.

You can use the global key hook up method mentioned over here: https://docs.microsoft.com/en-us/archive/blogs/vsod/using-shortcut-keys-to-call-a-function-in-an-office-add-in
