title: Looking for ALT+LeftArrowKey solution in zsh
body: <p>I just recently switched from bash to zsh, however I miss my <kbd>Alt</kbd>+<kbd>LeftArrowKey</kbd> and <kbd>Alt</kbd>+<kbd>RightArrowKey</kbd> to go back and forth a word at a time.</p>
  
  <p>Right now, if I press <kbd>Alt</kbd>+<kbd>LeftArrowKey</kbd> I go back a couple of letters and then I'm stuck. I won't go any further backwards and it won't back to the end of the line with <kbd>Alt</kbd>+<kbd>RightArrowKey</kbd> as I would expect. I can't even use the arrow keys to go to the end of the line, only to the second to last. Can't input new chars on the line either or indeed delete.</p>
  
  <p>How do I get my beloved shortcut back?</p>
  
  <p>I'm on Mac OS X using Terminal if that's important.</p>
