title: How to make a keymap within a list of a variable
body: <p>Could anyone give me some assistance, please, to <code>make-sparse-keymap</code> within the following example and create at least one sample entry within that new keymap.</p>
  
  <p>I'd like to create sub-menus to better organize and add additional entries to those sub-menus.  This example is borrowed from the function <code>menu-bar-update-buffers</code> within <code>menu-bar.el</code>, and I have adapted a modification of the function to work with a right-click <code>pop-up</code> context menu.</p>
  
  <pre><code>(setq lawlist-context-menu-command-entries
    (list
      '(command-separator "--")
      (list
        'next-buffer
        'menu-item
        "Next Buffer"
        'next-buffer
        :help "Switch to the \"next\" buffer in a cyclic order")
      (list
        'previous-buffer
        'menu-item
        "Previous Buffer"
        'previous-buffer
        :help "Switch to the \"previous\" buffer in a cyclic order")
      (list
        'select-named-buffer
        'menu-item
        "Select Named Buffer..."
        'switch-to-buffer
        :help "Prompt for a buffer name, and select that buffer in the current window")
      (list
        'list-all-buffers
        'menu-item
        "List All Buffers"
        'list-buffers
        :help "Pop up a window listing all Emacs buffers") ))
  </code></pre>

  <p><strong>EDIT</strong>:  Issue resolved --  I modified the example for creating the <code>Frames</code> menu folder as was done within <code>menu-bar-update-buffers</code> from <code>menu-bar.el</code>. See answer below.</p>
