Quick Start Guide
(for example, info ls). You can browse an info page with a viewer directly in the
shell and display the dierent sections, called “nodes.” Use [Space] to move for-
ward and [<—] to move backwards. Within a node, you can also browse with
[Page ↑] and [Page ↓] but only [Space] and [<—] will take you also to the previous
or subsequent node. Like for the man pages, press [Q] to end the viewing mode.
Note that man pages and info pages do not exist for all commands. Sometimes both
are available (usually for key commands), sometimes only a man page or an info
page exists, and sometimes neither of them are available.
