title: Key shortcuts in a web application
body: <p>I'm thinking about creating some keyboard shortcuts in my web application. But, most of the important shortcuts are already attached to the browser itself (like <kbd>F1</kbd>, <kbd>F2</kbd>, <kbd>Fn</kbd>; <kbd>Ctrl</kbd> + <kbd>N</kbd>; <kbd>Ctrl</kbd> + <kbd>P</kbd>, <kbd>Alt</kbd> + <kbd>P</kbd>, <kbd>Alt</kbd> + <kbd>A</kbd>, etc...)</p>
  
  <p>I've notice that the browsers don't use any <kbd>Shift</kbd> combination. But, <kbd>Shift</kbd> is already reserved to type uppercase letters, so, I think using <kbd>Shift</kbd> + <kbd>Key</kbd> combinations isn't a good idea.</p>
  
  <p><strong>Are there some guidelines to write keyboard shortcuts on the web?</strong></p>
  
  <p>Or, should I give up using it?</p>
