   2 <p>You must declare the "input" permission
   3 in the <a href="manifest.html">extension manifest</a>
   4 to use the input.ime API.
   5 For example:</p>
   6 <pre data-filename="manifest.json">
   7 {
   8   "name": "My extension",
   9   ...
  10   <b>"permissions": [
  11     "input"
  12   ]</b>,
  13   ...
  14 }</pre>

  18 <p>
  19 The following code creates an IME that converts typed letters to upper case.
  20 </p>
  21
  22 <pre>
  23 var context_id = -1;
  24
  25 chrome.input.ime.onFocus.addListener(function(context) {
  26   context_id = context.contextID;
  27 });
  28
  29 chrome.input.ime.onKeyEvent.addListener(
  30   function(engineID, keyData) {
  31     if (keyData.type == "keydown" && keyData.key.match(/^[a-z]$/)) {
  32       chrome.input.ime.commitText({"contextID": context_id,
  33                                    "text": keyData.key.toUpperCase()});
  34       return true;
  35     } else {
  36       return false;
  37     }
  38   });
