127 This example demonstrates a custom <a>CommandHandler</a>.
128 It uses localStorage as the repository for the clipboard, rather than an in-memory global variable.
129 It is defined in its own file, as <a href="LocalStorageCommandHandler.js">LocalStorageCommandHandler.js</a>.
130 </p>
131 <p>
132 Try copying and pasting between the above Diagrams, or between tabs/windows that contain Diagrams using LocalStorageCommandHandler.
133 Note that when copying and pasting between Diagrams, it will work best if they have similar templates.
