The entire set of context nodes is called a vault. This set of nodes has it's own file and is loaded when the browser points, via 'localhost', to an .html file hosting the vault.
When the 'save' action is clicked, the vault is saved to disk permanently, written in the JSON format. This action does not cause content files to be saved. Saving the content documents, even if they are opened from within the UD app, is something that happens independently from saving the vault that references those documents.
When the 'close' action is clicked, this can cause documents to be saved when users confirm the action. No changes to the vault occur by opening and closing items.
Whether a document is opened or closed is remembered by the UD app, this state is not forgotten if ever the browser decides to crash. On the other hand, the existence of those documents might not be recorded in the vault if it is not saved and the tab in which UD app runs is closed. It is recommended that changes to the vault that you wish to keep should be saved without much delay.
Navigating the vault
To highlite an item or a node click on it. The UP and DOWN ARROW keys move the selection around. The following shows a dark blue dotted line indicating selection of an item:

Once a context node is selected, you can use the ENTER button to make that the 'scope item'. The scope item displays its title and its visible descendants, including all descendant resources. It also determines the presentation formatting that is applied to all descendants that become visible.
To get back to the parent node, you click on the parent in the path string above the main content window. Then press ENTER.
Opening and closing resources
To open an item just select it and click on the 'open' menuitem.
You will then see either a new browser tab with your item opening up, or a new document window or possibly an application window. Applications are chosen based on the file extension and how the system associates apps with file extensions. The file extensions that are valid for opening are limited to those that are supported by the AppleScript "open" command for the Mac, and the "start" command for Windows.
A solid green circle [ ] indicates that a particular file or browser url is currently open.
Working with pre-established groups
Significant productivity gains will happen when you start to work with groups of items, be it urls, files, or both simultaneously. Operations on groups include 'open', 'close' and 'tag'.
To open or close a group of items you first start group mode by pressing the 'g' key. This must be done when no text fields are recieving keyboard input. Once you have gone into group mode, a couple things change. First, you will notice that the group membership info is visible for all of the resources (inside the orange curly braces). Secondly you will see that the 'open' and 'close' commands now have options for directing the command action to groups...
Creating and working with customized groups
You first create a customized group by using the 'tag' action. Three possible ways to select items for a tagging action are 1) tag a selected item, 2) tag open items that are children of the same parent item, and you can 3) tag any and all open items. These are reflected in the following menu:
Once you have clicked a tagging option you should see a pop-up box with an empty edit field. Type the group name you would like to use into the field and click 'OK'. The example below shows an updated membership status when the 'tag -> selected item' action was used and the group moniker "urgent" was provided and OK'ed in the pop-up box:
Finally we're ready to open a customized group that we have created. This is just a matter of going to the 'open' menuitem and finding the custom group that now appears in the submenu.
