title: How do I add text to the location of a user's cursor in a Rich Text Box in C#?
body: <p>In Visual C#.NET:</p>
  
  <p>How do I add/append text directly to where the user's cursor is in a Rich Text Box?</p>
  
  <p>For example, if the user clicked a button, and their cursor was somewhere in the rich text box, text would be immediately added to the location of their cursor.</p>
