How to perform .Onkey Event in an Excel Add-In created with Visual Studio 2010?

Question

I am creating an Excel Add-In using Visual Studio 2010. I would like to run some code when users clicks a combination of keys.

Here is the code I have got

Answer 1

First thing A1, A2, A3 are considered as cell address.

1. Create .xlsm file and add these VBA code

   Sub AOne()
   MsgBox "Message from AOne"
   End Sub
   
   Sub ATwo()
   MsgBox "Message from ATwo"
   End Sub
   
   Sub AThree()
   MsgBox "Message from AThree"
   End Sub
   

2. Now create a Excel Workbook project in Visual studio and add existing file and choose the above created .xlsm file

   private void ThisWorkbook_Startup(object sender, System.EventArgs e)
   {
       EnableShortCut();
   }
   
   private void ThisWorkbook_Shutdown(object sender, System.EventArgs e)
   {
   }
   
   public void EnableShortCut()
   {
       Excel.Application app = Globals.ThisWorkbook.Application;
       app.OnKey("+^{U}", "AOne"); //action A1 should be performed when user clicks  Ctrl + Shift + U
       app.OnKey("+^{L}", "ATwo");//action A2 should be performed when user clicks  Ctrl + Shift + L
       app.OnKey("+^{P}", "AThree"); //action A3 should be performed when user clicks  Ctrl + Shift + P
   }
   

Run your project this should work, Application.OnKey in Excel or Application.Keybindings in Word takes the Macro name as parameter.
