title: How to enter 'NULL' into SSMS cell?
body: <p>In SQL Server Management Studio 2012, I was typing/pasting data into a table (via Edit Top 200 Rows).
  Whenever I typed/pasted <code>NULL</code> in a cell, a <code>NULL</code> value was inserted. Apparently it thought I meant the <code>NULL</code> value instead of the <code>'NULL'</code> text. Which didn't work, as my column wasn't nullable...</p>
  
  <p>Now how do I enter the <code>'NULL'</code> text into a cell?</p>
  
  <p>If I wanted to insert the <code>NULL</code> value, I would have pressed <kbd>Ctrl</kbd>+<kbd>0</kbd>...</p>
