You can move through the file from node to node in strict sequence by typing `C-c C-p C-[' (para-goto-previous-node-in-sequence) or `C-c C-p C-]' (para-goto-next-node-in-sequence)
Also, if your cursor is in the upper left hand corner of the window, or if the buffer is read-only, you can use the Info mode commands, which are single keys such as `b' and `n'. These commands execute `para-beginning' and `para-next' just as `C-c C-p C-b' and `C-c C-p C-n' do. All the movement commands have keybindings.
If your cursor is in the upper left hand corner of the window, or if the buffer is read-only, you can scroll forward by typing SPC and scroll backward by typing DEL. You can combind the SPC scrolling command and the `]' node movement command to move though the complete file.
You can select a node listed in a menu by typing `C-c C-p 1', `C-c C-p 2', etc., to go to the first node listed, the second node listed, etc.; or you can place the cursor over the name of the node, type `C-c C-p C-m' (para-menu) and then type the menu name (or part of it), followed by pressing RET. (The `para-menu' command will even take you to another file.)
To go to the next node in this file, type `C-c C-p C-n'.
Or, if your cursor is in the upper left hand corner of the window, or if the buffer is read-only, type `n'.
