The cseligman.com Toolbar (shown above) is meant to provide easy navigation and access to my site for my students (and other users of my site), by including all Site Map and External links in a drop-down Links menu, and all eText links in a drop-down eText menu. Students are not required to use the Toolbar, but I'd strongly recommend its use by anyone who has trouble finding specific pages on my site.

Downloading and Installing the Toolbar
    To download and install the Toolbar, just click on the image above, then click Run when prompted by the File Download Security Warning. The file will self-install, and the Toolbar will appear, more or less as shown.

Toolbar Items
     Running from left to right, a newly installed Toolbar will usually have the following items/buttons:
     Toolbar identification showing that you are looking at the cseligman.com toolbar. Clicking on the name takes you to my Home Page.
     A drop-down Toolbar menu can be used to customize the Toolbar. Most of the items on the drop-down menu are self-explanatory, and can be learned by playing with it. For instance, Shrink Toolbar removes the text labels on Toolbar items, and if that has been done, Unshrink Toolbar restores the labels. Toolbar Options allows you to delete or add items to the Toolbar, and in some cases, modify the behavior or display of the items. See Links, below, for another use of this menu.
     The Google Search Box is essentially the same as any other search box; but the Search Results page displays my "logo" (the name of my site) at the top. Clicking on the logo takes you to a page where you can search in the normal way, or limit your search to the contents of my site. Note: The Search link at the top of each page already provides a real-time search of the site.
     The Links Menu includes, as noted above, every link on my Site Map and External Links pages, along with many other links which I find more or less useful. When I add new Links or repair broken ones, your Toolbar may or may not automatically include the changes. To ensure that links are up-to-date, Refresh or Upgrade the Toolbar once in a while (Upgrade reinstalls the Toolbar, while Refresh updates it without reinstallation; both are found on the Toolbar drop-down menu, next to my logo).
     The eText Menu includes every current link from the Table of Contents for my Online Astronomy eText/Supplement, and will be updated to include any new links/pages, as I post them.
     The Radio Menu plays online radio streams. The Toolbar comes with a built-in radio (as noted below), which is user-customizable; but I've had some problems with it, and installed my own radio menu, to use when I can't get the built-in radio to work.
     An E-Mail Notifier (not shown in the image above) alerts you to any new email (once properly set up for your accounts).
     The Online Radio Player (not shown in the image above) is a fully customizable streaming radio player, preloaded with dozens of stations. I've had problems with it taking forever to connect or never connecting, but if you don't have such problems, you'll probably prefer it to my radio.

Link Additions and Suggestions
     The Links menu already contains all the links on my Site Map and External Links pages, and a hundred or two other links which I think might be of general interest; but I will be adding more links, over a period of time, and am open to suggestions as to what links to add, and where to add them to the Link menu (or to a 'More Links' menu, if the first one gets too unwieldy). If you have any link suggestions, please feel free to send them to courtney@cseligman.com.
