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.
