Browser

A browser is a window with a subset of elements belonging to the currently opened collection. Browsers for various element subsets are available from the View menu (only at Middle and Professional levels).

This is an exemplary browser window:

SuperMemo Browser - Windows API subset

With the green-yellow alignment button on the browser toolbar, you can align the browser to the left along with the element window to the right. This way you can preview individual elements as the selection in the browser changes (only if the synchronization button is down as in the picture). A right-click over the browser area opens the browser menu with advanced operations on the browser.

A browser window is made of the following components:

  • Caption - name of the browser and the number of elements displayed in the browser (in the above example, 751 elements containing the case-insensitive text "api: " are displayed)
  • Toolbar - buttons providing access to the most often used browser operations (the first button also opens the browser menu)
  • Element list - list of elements included in the browser with the following columns (you can change the size and the order of the columns by dragging their gray headers):
    • Sel - click on this field to select the current entry (e.g. to include it in a newly generated element subset). The selected entry is marked with the plus sign in the Sel column. Selections are useful in processing element subsets
    • Title - title of the element
    • NextRep - date of the next repetition of the element
    • LastRep - date of the last repetition of the element
    • Dif - difficulty of the element in percent (the darker the field, the more difficult the item)
    • Reps - number of times the displayed element has been repeated in learning (since the last time it was forgotten or since the time it was first learned)
    • Laps - number of times the element was forgotten
    • Type - type of a given element: topic, item or task (see also: Topics vs items). See: knowledge tree to understand icons and colors
    • FI - requested forgetting index of the element 
    • Intrv - current interval of the element. This is the difference between LastRep and NextRep in days 
    • Delay - the degree of delay of an element in the learning process
    • No - position of the element in the browser (i.e. number of the row)
    • Ord - ordinal number of the displayed element (e.g. used in sorting the pending queue)
    • ElNo - physical number of the element in the collection. This number may be greater than the total number of elements listed in statistics, esp. if you have deleted many elements. Those numbers never change, therefore, once you delete a group of elements, it will take some time before the freed element numbers are reused
    • AF - A-Factor associated with the element (see: SuperMemo Algorithm)
    • Post - the number of times the element has been delayed with Postpone 
    • UF - U-Factor associated with the element (see: SuperMemo Algorithm)

Some of the browser fields listed above allow of sorting the browser. Click on the field's caption to sort the browser. For example, to sort the browser by the last repetition date, click LastRep. The elements in the picture are sorted for the Title field
