The introductory course is almost over; please continue a little longer to learn some intermediate-level commands.
Most Info files have an index, which is actually a large node that contains nothing but a menu. The menu has one menu item for each topic listed in the index. You can find the index node from the main menu of the file, with the m command; then you can use the m command again in the index node to go to the node that describes the topic.
There is also a short-cut Info command, i, which does all of that for you. It searches the index for a given topic (a string) and goes to the node which is listed in the index for that topic. See Info Search, for a full explanation.
If you have been moving around to different nodes and wish to retrace your steps, the l command (l for last) will do that, one node-step at a time. As you move from node to node, Info records the nodes where you have been in a special history list. The l command revisits nodes in the history list; each successive l command moves one step back through the history.
If you have been following directions, an l command now will get
you back to
Help-M. Another l command would undo the
u and get you back to
Help-FOO. Another l would undo
the m and get you back to
In Emacs, l runs the command
>> Try typing three l's, pausing in between to see what each l does. Then follow directions again and you will end up back here.
Note the difference between l and p: l moves to
where you last were, whereas p always moves to the node
which the header says is the
Previous node (from this node, the
Prev link leads to
The d command (
Info-directory in Emacs) gets you
instantly to the Directory node. This node, which is the first one
you saw when you entered Info, has a menu which leads (directly or
indirectly, through other menus), to all the nodes that exist. The
Directory node lists all the manuals and other Info documents that
are, or could be, installed on your system.
>> Try doing a d, then do an l to return here (yes, do return).
The t command moves to the
Top node of the manual.
This is useful if you want to browse the manual's main menu, or select
some specific top-level menu item. The Emacs command run by t
Clicking Mouse-2 on or near a cross reference also follows the reference. You can see that the cross reference is mouse-sensitive by moving the mouse pointer to the reference and watching how the underlying text and the mouse pointer change in response.
>> Now type n to see the last node of the course.
