Hi shahrzad
You create that manually, create a jump in branch table 2 that links back to branch table 1 (using the latest version from the mods
download).
If you wanted to create links to all pages on a particular page like a table of contents, create a branch table with buttons that linke to all the pages, then create a link on the other pages back to this branch.
By the way, in a few days we have some new code for lesson that has an automated previous link, like the next link. We're also working up a 'slide show mode' with a configurable size for the screen (ie 640x480), with bg color and bg image that can be customized, and in this mode the buttons will line up horizontally.
We have most of this done, we have a few more things to polish up and then we'll post a link to download the code here for folks who want to try it out.
