A family of Microsoft word processing software products for creating web, email, and print documents.
Without programming a new class event to intercept your typing, you can't get a dynamic character count to display on the status bar and, if you did, it would probably prevent anything else displaying there.
You could, though, use a macro like the following and assign a keyboard shortcut to it:
Sub CharCount()
Application.StatusBar = "Character Count = " & ActiveDocument.Characters.Count
End Sub
The above macro temporarily takes over the status bar to display the character count. It gets hidden again as soon as you resume whatever you were doing.
