title: How to change emmet shortcut key in netbeans?
body: <p>In netbeans(7.4) I installed <strong>emmet</strong> plugin.<br>
  I have to use <kbd>ctrl</kbd>+<kbd>alt</kbd>+<kbd>n</kbd> to trigger code completion.<br>
  I want to replace it with <kbd>tab</kbd> key.<br>
  I searched <kbd>ctrl</kbd>+<kbd>alt</kbd>+<kbd>n</kbd> in keymap in the <strong>option</strong>-><strong>keymap</strong>. There isn't one.<br>
  Why? I can trigger code completion with <kbd>ctrl</kbd>+<kbd>alt</kbd>+<kbd>n</kbd> though.<br>
  How can I set it to <kbd>tab</kbd> key? </p>
