things to do onmousedown in outline view * /*
*   To Do:  This big event handler needs to be replaced by lots
* of little ones individually connected to each icon.  This horrible
* switch below isn't modular. (Sorry!) - Tim
 expand collapse refocus select visit/open a page
function expandMouseDownListener (e) { // For icon (UI.icons.originalIconBase + 'tbl-expand-trans.png')
    var target = thisOutline.targetOf(e)
    var p = target.parentNode
    var subject = UI.utils.getAbout(kb, target)
    var pane = e.altKey ? panes.internalPane : undefined // set later: was panes.defaultPane

    if (e.shiftKey) { // Shift forces a refocus - bring this to the top
      outlineRefocus(p, subject, pane)
    } else {
      if (e.altKey) { // To investigate screw ups, dont wait show internals
        outlineExpand(p, subject, {
          'pane': panes.internalPane,
          'immediate': true
        })
