So, suppose you're on B and move +% forward, then you show B and go to C. And +% if you move forward again, you show C and +% go to the unnamed node between parentheses. +% Which is like any other node. If you go backward, +% you hide C and go to C, etc. +% Now, PresSteps is special, it's a slippery place. +% Note that you can't reach it by a step: A has no +% Prev entry. You go to PresSteps only when you +% arrive on a page, and if you arrive by moving +% forward Next becomes the new node immediately +% (no need to move forward to reach A, otherwise +% you'd need two clicks to make it appear). On the +% other hand, if you come by moving backward, then +% Prev becomes the current node immediately, and +% you can see what it does: if you move forward, it +% goes to the next page, and if you move backward, +% you hide C and make it the current node. +% PresSteps also contains a PA and NA, which are +% executed under the same circumstances; the NA +% contains the list of steps of the page and their +% original visibility; hence when one arrives on a +% page, this visibility is restored. PA contains +% the succession of actions made thoughout the page; +% hence, when one arrives on it backward, this succession +% of action is executed and one sees the completed page. +% Thus, one avoids discrepancy between navigation and +% step visibility. +% +% To say it otherwise, PresSteps is the gate to the +% page, and you have to go through the gate to reach +% the steps (they aren't linked together from one +% page to the other. +% +% And I'm not really lecturing on PDF here. I'm just +% trying to write things down while I understand them. +\endinput
