Most important operations on the knowledge tree displayed in the contents window are available from the contents pop-up menu. To open this menu press Alt+F10 or right-click over the contents window.

The contents pop-up menu includes the following options:

• View - bring the element window to the front and display there the currently selected contents element
• Review - review material belonging to the currently selected branch in the knowledge tree
• Edit - edit operations (also available from buttons at the bottom of the contents window)
  • Add - add a new element as a child of the currently selected element (a child is an element that is one level down in the knowledge tree)
  • Sibling - add a new element as a sibling of the currently selected element (a sibling is an element is is on the same level in the knowledge tree)
  • Insert - insert a new element in the place of the currently selected element (the current element moves one position down)
  • Delete - delete the currently selected element and all its children (if any)
  • Title - edit the title of the currently selected element (note that you can also edit the title in-place if you click the currently selected element)
• Search - search for titles
  • Find - find a string in the first title in expanded branches below the currently selected element
  • Find next - repeat the last search done with Search : Find
• Category - options for managing contents categories
  • Create new category - create a new contents category with the currently selected element as the root. The category will take the title of its root element as its name. You can change that to a shorter or more mnemonic name. The currently selected element will also become the first hook of the category
  • Make root - make the currently selected element the root of the current category (the current category is the category selected in category combo-box on the toolbar). The root is the element that is the ascendant of all elements in the category
  • Make hook - make the currently selected element the hook of the current category (the current category is the category selected in category combo-box on the toolbar). Once you change the hook, all newly added elements will be children of the hook (only within the current category)
• Node operations - operations that consider all children or all descendants of a given branch
  • Status
    • Remember - introduce the whole branch into the learning process
    • Forget - remove all elements in the branch from the learning process
    • Dismiss - dismiss all elements in the branch
    • Undismiss - add all dismissed elements in the branch to the pending queue and remove their dismiss status
    • Make items - make all elements in the branch items (see also: Topics vs items)
    • Make topics - make all elements in the branch topics
    • Reset history - reset the repetition history of all elements in the branch
  • Forgetting index - change the forgetting index in the entire branch
    • Set forgetting index - assign a given forgetting index to all elements in the branch
    • Default forgetting index - make all elements in the branch use the default forgetting index. The default forgetting index is set with Tools : Options : Learning : Forgetting index
  • Ordinal - change the ordinal number in the entire branch
    • Set ordinal - give all elements the same ordinal number
    • Set position ordinal - give all elements ordinal numbers equal to their physical position in the collection (e.g. to sort the pending queue in the order of adding elements into the collection)
    • Set pending ordinal - give all elements ordinal numbers equal to their position in the pending queue
    • Spread ordinals - give all elements ordinals increasing in equal steps from a given lower limit to a given higher limit
    • Modify ordinal - increase or decrease ordinal numbers in the entire branch
  • Template - template operations on the whole branch
    • Merge with template - merge all elements in the branch with a given template (see Using templates)
    • Add template - add a template to all elements in the branch (see Using templates)
  • Set title - set a given title
• Count - count all elements matching some criterion
  • Items - count all items in the branch (see also: Topics vs items)
  • Topics - count all topics in the branch
  • Memorized - count all memorized elements in the branch (i.e. elements that take part in repetitions)
  • Pending - count all pending elements in the branch
  • Dismissed - count all dismissed elements in the branch
• Tools
  • Arrange in folders - group all elements in the branch into a number of branches with equal number of children. For example, if your branch contains 100 elements, you can use Arrange in folders to create 10 empty elements used as placeholders for the remaining items. Each of those newly created elements will host 10 children. Thus all your 100 items will be grouped in 10 branches with 10 children each
  • Browse node - put all descendants of the currently selected branch in the element browser
  • Transfer node - transfer the entire collection to another collection
  • Save as subset - save all elements in the branch in an element subset (see: Using subsets)
  • Export as text - export all elements in the current branch as text
  • Export learning - export the learning process from all elements in the current branch
  • Random test - run a random test on all elements in the current branch
  • Move empty elements - move all empty elements to a selected branch in the collection
• Customize
  • Font - change the font used in the contents window
• Switch window - switch to the element window (the same shortcut, Ctrl+Shift+W, will take you back from the element window to the contents window)
