title: Capturing TAB key in text box
body: <p>I would like to be able to use the <kbd>Tab</kbd> key within a text box to tab over four spaces. The way it is now, the Tab key jumps my cursor to the next input.</p>
  
  <p>Is there some JavaScript that will capture the Tab key in the text box before it bubbles up to the UI?</p>
  
  <p>I understand some browsers (i.e. FireFox) may not allow this. How about a custom key-combo like <kbd>Shift</kbd>+<kbd>Tab</kbd>, or <kbd>Ctrl</kbd>+<kbd>Q</kbd>?</p>
