NAVIGATION:

    l goes to the previous node that you VISITED, i.e.  it "backs out" 
    of the node you are in.

    Menu sequence is to visit each node of a menu in turn, without
    visiting any sub-menus.  The n and p commands navigate like this.
    (Navigating like this, you can never get below the first menu level).

    Linear sequence will visit all nodes in depth-first sequence.
    Use the space bar and backspace/del keys to navigate like this.

SCROLLING   Arrow keys
            space-bar & backspace or DEL
            You will go to next or prev node if you are at very beginning or
	    end of the current node.
	    (PageUp and PageDown are just like space/bs/DEL, except will not
	     leave the current node).

NODE NAVIGATION  n p space-bar 
    l  Goes back to the previous node you were on.
       (Note that this could put you deeper into the node tree if you had
       previously backed out).
    n  Always goes to the Next node at the current level (or to the first
       menu node if at Top).
       There will be no 'n' available if you are at the last node of a
       menu (except for Top).
    p  Previous node at current level.  This is NOT the previous page that
       you were on, it is the node previous to this in its menu.
       There will be no 'p' availabel if you are at the first node of a
       menu (except at First level below Top).
    spacebar (when at bottom of a node)
        Go to the next node in a depth-first sequence.
    backspace/Del (when-at-top-of-a-node)
        Go to the previous node in a depth-first sequence.

TUTORIAL  h


MENUS
    Always start with "* Menu"
    Menu item:  "Brief name: node.  Any text" (or "node:: Any text").
    Tab to traverse the menu items (without going into them)
    ENTER on a menu item line to go into the menu
    BACK OUT OF MENU NODE u  (for Up)
    ABORT INTERACTION: Ctrl-g

CROSS-REFERENCES
    Cross references are exactly like Menu items, but the target nodes
    are not sub-menu nodes of the parent node.  Therefore, the p and u
    commands won't get you back to anyplace you were before.
    BACK OUT OF CROSS-REF NODE l  (for Last)
