speedbar: Info

 
 5.2 Info
 ========
 
 When browsing Info files, all local relevant information is displayed in
 the info buffer and a topical high-level view is provided in speedbar.
 All top-level info nodes are shown in the speedbar frame, and can be
 jumped to by clicking the name.
 
    You can open these nodes with the ‘[+]’ button to see what sub-topics
 are available.  Since these sub-topics are not examined until you click
 the ‘[+]’ button, sometimes a ‘[?]’ will appear when you click on a
 ‘[+]’, indicating that there are no sub-topics.
