Please type "T". Just one character; no CR after it. You are talking to a program INFO, used for reading documentation. INFO documentation files are structured into units called "Nodes". A node usually contains information on a particular topic at a particular level of detail, and names of other related nodes. The purpose of the INFO program is to help you move from one node to another. This node contains the beginning of the course on how to use INFO. This is a form of programmed instruction in which the text will tell you how to use INFO commands to continue reading the text. ">>" in the left margin will be used to mark directions which should be followed immediately. The "T" command which you typed told INFO to type the entire contents of the node, which is what it is now doing. Because you are using a printing terminal (or so the system believes), when you first move to a node INFO will print only the first four lines, as it did. To see the rest, you must type "T". The intention is that from those four lines you will get an idea of whether you want to see all the rest. The top line of a node is its "Header". This node's header, which said "File: INFO Node: Help-Printing Next: Help-Print-P" in case it's off your screen now) says that it is the node named Help-Printing in the file "INFO". It says that the Next node after this one is the node called "Help-Print-P". An advanced INFO command lets you go to any node whose name you know. Besides a "Next", a node can have a "Previous" or an "Up". You can tell that this node doesn't have either of those, because there is none visible in the header. The line that follows that Header is called the Title. This node's title is peculiar in that it gives the directions "Please type 'T'", but most nodes' titles just say what the node is about. Now it's time to move from this node to the Next one, which is Help-Printing-Space. To do that, type "N" for Next. INFO will look in the header to find which node is next after this one and then go there. >> Type "N". After the header and title are printed, type "T" again.
