The Studio has the possibilty of a ‘jump list’ or breadcrumbs path, showing the steps a user has already taken, and allowing her to ‘jump back’ to an earlier step. Any node with an user-interface may be added to the jumplist. Nodes that do not have a userinterface are not shown to the end-user, so jumping to them is not possible. If there is no user interface, the jumplist is disabled.
To add a node to the jumplist click the button
Layout > Jumplist:
Now check the box and fill in the title by which you want identify the step in the jumplist at the description:
Add hierarchy with Menu indent: the indentation will make clear that the steps in certain nodes are part of a larger step started in an earlier node, like this:
Once you have added a description, the icon will change.
This way, you can see if there is a description without having to open de window. You can toggle the description on and off by pressing
[Ctrl+J]. If there is no description yet, the Studio will take the name of the node as description.
Keeping your jumplist working after stepping or jumping back
Besides jumping back to an earlier item it is possible to jump ahead, but only as long as the path has not changed due to changed answers. Once the program recognizes that a changed answer renders it impossible to take the same path the jumplist will be cut off at the spot where it would diverge. In the next example we jumped back from conclusion to the step called condition. We may jump ahead from condition as long as the answer to the question ‘What is your age’ remains 17. Had we changed it, the decision tree would go along a different path. The jumplist will keep ‘future’ nodes in the jumplist, as long as they are relevant, this is an option in de server. Normally this option in on, but it is possible to turn it off.
Variable values in the jumplist
You may quote a variable value in the jumplist using the usual caron syntax:
