title: How to properly bind cider-switch-to-repl-buffer to <C-tab>?
body: <p>I tried</p>
  
  <pre><code>(eval-after-load 'cider
    '(progn
       (define-key cider-mode-map (kbd "&lt;C-tab&gt;") 'cider-switch-to-repl-buffer)
       (define-key cider-repl-mode-map (kbd "&lt;C-tab&gt;") 'cider-switch-to-repl-buffer)))
  </code></pre>
  
  <p>But it only works in the buffer, i.e. I can switch from the buffer to the repl, but not the other way around. What I'm trying to achieve is to use <kbd>C-tab</kbd> to switch back and forth between the buffer and the repl.</p>
  
  <p>Thanks!</p>
