Bookmarklet ?

Bookmarklets are tiny programs stored inside bookmarks. Similar to add-ons, extensions, and user scripts, they add new tools to your web browser. Bookmarklets are shared on web pages as web links. You don't actually "install" a bookmarklet. You simply add it to your bookmarks. It just sits there patiently until you want to use it.

Install (default)

  1. Copy the content of shortcutToSpeech.js (click RAW then hit ctrl+a then ctrl+c)
  2. Go to http://ted.mielczarek.org/code/mozilla/bookmarklet.html
  3. Read instructions
  4. Put a name e.g. duolinguo speech, paste, crunch
  5. Drag the generated bookmarklet to your bookmark bar

Install (setting your own shortcut)

  1. Go to http://keycode.info/ and get the key code of the new shortcut you wish to set
  2. Copying the content of shortcutToSpeech.js in your text editor
  3. Click the RAW button (top of the file)
  4. crtl+A then crtl+C
  5. Look for the line with if(event.keyCode ===...
  6. Replace the numeric value with the keycode from step 1
  7. Jump to the step 2 of Install (default)

Note: If your bookmark bar is hidden, google how to display it..
