title: toad for oracle autocomplete dropdown
body: <p>Toad for Oracle has an autocomplete feature.. you type <code>SELECT * FROM USER.</code> and then press <kbd>Ctrl</kbd>+<kbd>.</kbd> and a drop down appears where you can choose from the objects available to you.</p>
  
  <p>This functionality suddenly stopped. Now, instead of a drop down, it goes to the first default match. I have no idea what I did to change the behavior.</p>
  
  <p>How do I restore the drop down functionality?</p>
