title: How do I forward `<Ctrl>-<Tab>` in Konsole?
body: <p>I want to use intelligent tabbing in Emacs in C++ mode, but I also want to be able to insert a tab character when necessary.  From other posts, I gather that the easiest way is to bind <code>&lt;Ctrl&gt;-&lt;Tab&gt;</code> to indent.  However, it appears that Konsole in KUbuntu won't forward the <code>&lt;Ctrl&gt;</code>?</p>
  
  <p>My current .emacs file contains:</p>
  
  <pre><code>(defun my-c-mode-common-hook ()  
   (setq c++-tab-always-indent t)
   (setq tab-width 4)
   (setq indent-tabs-mode t)
   )
  
  (add-hook 'c-mode-common-hook 'my-c-mode-common-hook)
  
  (global-set-key [C-tab] 'self-insert-command)
  </code></pre>
  
  <p>So I believe that this will bind <code>&lt;Ctrl&gt;-&lt;Tab&gt;</code> to inserting a tab character.  However, when I run:</p>
  
  <p><code>&lt;Ctrl&gt;-h k &lt;Ctrl&gt;-&lt;Tab&gt;</code></p>
  
  <p>Emacs only reports that I pressed the tab key.  Is there some option to Konsole (which I have searched through to no avail) or global preferences in KUbuntu that I need to set so that the <code>&lt;Ctrl&gt;-</code> is also forwarded?  (It certainly forwards all of the other <code>&lt;Ctrl&gt;-blah</code> commands.)</p>
