title: Is there any way to extend the editor in SSMS?
body: <p>Can the SQL Server Management Studio text editor be extended? If it's possible, what kind of work &amp; tools are involved?</p>
  
  <p>I find myself frequently jumping to other editors for certain kinds of text manipulation, and then jumping back to SSMS. If it were possible to extend the SSMS editor, I might do so. </p>
  
  <p>The first feature I would add would be a "column mode" where you could operate on rectangles of text. UltraEdit, Emacs and few other editors have this feature. I find it invaluable for editing SQL.</p>
