Most important operations on element browsers are available from the browser pop-up menu. To open this menu press Alt+F10 or right-click over the browser window.

The browser pop-up menu includes the following options:

• View - bring the element window to front with the currently selected element (Enter or Ctrl+Enter)
• Learn - make all outstanding repetitions on items included in the browser. Once this is done, proceed with memorizing new elements from the browser
• Search
  • Find - find the first element in the browser with a title containing a given string. The search begins starting with the element that follows the currently selected element
  • Find next - repeat the last search operation with Search : Find (e.g. to search for the next element with the same string)
  • Find all - find all elements containing a given substring in their title and open these elements in a new browser
• Sort - sort the browser by a given column
  • By title - sort the browser alphabetically by the element title
  • By element number - sort the browser by the element number (column ElNo)
  • By ordinal number - sort the browser by ordinal numbers
  • By repetitions - sort the browser by the number of repetitions afforded each element (i.e. the number of times each element was repeated)
  • By forgetting - sort the browser by the number of memory lapses, i.e. the number of times each element was forgotten
  • By last repetition - sort the browser by the date of the last repetition
  • By next repetition - sort the browser by the date of the next repetition
  • By difficulty - sort the browser by the estimated difficulty of elements
  • By forgetting index - sort the browser by the requested forgetting index
  • By type - sort the browser by their type (item, topic or task)
  • By A-Factor - sort the browser by A-Factor
  • Randomize - randomly mix up the contents of the browser 
• Subset - subset operations (read also: Using subsets)
  • Select element - mark the currently selected element as part of a subset. Marking is most easily done with Ins. Marked elements have a plus sign in the leftmost column. You can later process marked element with other options such as Subset : Save selection or Child : Selected
  • Select all elements - mark all elements in the browser as a subset
  • Save selection - save all marked elements in a subset file (see Select element above)
  • Save all - save the whole contents of the browser in a subset file
  • Select browser range - mark all elements in the rows numbered in a given range. For example, if you input the range 10-20, the elements in the rows numbered from 10 to 20 will be marked as part of the subset
  • Select element range - mark all elements with numbers falling in a given range. Element number expresses the elements physical place in a given collection and is used as a unique element identifier. Element number is displayed in the column ElNo
  • Unselect browser range - unmark all elements in the rows numbered in a given range
  • Unselect element range - mark all elements with numbers falling in a given range
  • Unselect-Subtract - unmark all elements that belong to a given subset file
  • Unselect-Intersect - unmark all elements that cannot be found in a given subset file
  • Add subset file - create a new browser with the sum of the current browser and a subset file
  • Subtract subset file - create a new browser with the difference of the current browser and a subset file (i.e. containing all elements that belong to the browser and do not belong to the subset file)
  • Intersect subset file - create a new browser with the intersection of the current browser and a subset file (i.e. containing all elements that belong to both the browser and the subset file)
  • Delete - delete a subset file
• Child - open a child browser with a subset of elements stored in the currently used browser
  • Branch - open a child browser with all elements that both belong to the currently opened browser and a selected branch in the contents window
  • Outstanding - open a child browser with all outstanding elements of the currently opened browser. This option is particularly valuable if you would like to reschedule all outstanding items in a given branch of knowledge. In such a case you have to: (1) choose the branch in the contents window, (2) choose View : Selected branch (in the contents window), (2) choose Child : Outstanding (in the browser) and (3) choose Process browser : Learning : Reschedule (in the browser)
  • Memorized - open a child browser with all memorized elements contained in the current browser
  • Pending - open a child browser with all pending elements contained in the current browser
  • Dismissed - open a child browser with all dismissed elements contained in the current browser
  • Items - open a child browser with all elements that are items
  • Topics - open a child browser with all elements that are topics
  • Tasks - open a child browser with all elements that are tasks (i.e. belong to any of SuperMemo tasklists)
  • Selected - open a child browser with all elements that are marked with a plus in the leftmost column (see Subset : Select element above)
• Random
  • Random review - jump to a randomly picked element in the browser. This option is useful in quickly reviewing the material contained in the browser
  • Random test - start random test on the contents of the browser. All elements will be repeated in the standard way but the repetitions will have no effect on the learning process
  • Random learning - start random learning the elements in the browser. Memorized elements will not be affected but the pending elements will be memorized
  • Randomize browser - randomize the contents of the browser
• Tools
  • Export as text - export all elements in the browser as a text file with all learning process included. Such a file can later be imported to another collection
  • Export Q&A text - export all elements in the browser as a text file of questions and answers. Such a file can later be imported to other versions of SuperMemo (e.g. SuperMemo 6 for DOS, SuperMemo 7 for Windows, SuperMemo 1.0 for Windows CE, SuperMemo 1.0 for Palm Pilot, etc.)
  • Export all texts - export all elements in the browser as a text file that includes only the texts used by the browser elements (no learning information will be included)
  • Transfer - transfer all elements in the browser to another collection
  • Save pending - save elements from the browser in the pending queue (this option is only active if you are using a browser with the contents of the pending queue). You can use this option to sort the pending queue by ordinal numbers, by title, etc. For example, to sort the pending queue by the element number: (1) choose View : Pending, (2) click the column ElNo, and (3) choose Tools : Save pending on the browser menu
  • Save drill - save elements from the browser in the final drill queue. The old queue will be overwritten. You can use this options to drill a subset of elements (e.g. on the day before an important examination)
  • Save repetitions - save elements from the browser of outstanding items in the repetition schedule. You can use this option to sort outstanding repetitions (e.g. for difficulty, interval, etc.)
  • Repetitions graph - display a graph that shows the correlation between the number of repetitions and the interval reached by elements included in the browser

• Process browser - process all elements contained in the browser, e.g. memorize all pending elements, move the elements to another category, etc. Operations available from Process browser are identical to those available from Process branch on the contents window's pop-up menu
  • Learning
    • Reschedule - reschedule all elements equally in a given period of time (e.g. make sure that all items related to geography are rescheduled in equal portions of 20 items per day in the period of one month). Please note that you might want to first choose Child : Outstanding (see above) to make sure that you reschedule only outstanding repetitions, i.e. not all repetitions in the entire branch. You can also choose Child : Items to make sure you reschedule only item repetitions
    • Postpone - increase intervals of all outstanding repetitions by a selected factor (e.g. 1.02 will increase intervals by 2%). All intervals will increase proportionally but by no less than 1 day
    • Dilute - same as Postpone but with this difference that all elements in the browser will be affected (not only outstanding elements)
    • Remember - memorize all elements that have not yet been memorized
    • Forget - remove all memorized elements from the learning process and put them at the end of the pending queue
    • Dismiss - dismiss all elements, i.e. ignore them in learning
    • Undismiss - return all dismissed elements to the pending queue
    • Add to drill - add all elements to the final drill queue
    • Reset history - reset the repetition history of all elements
  • Move
    • To a branch - move the elements to a selected branch in the knowledge tree
    • To a category - move the elements to a selected category
  • Status
    • Make items - convert all elements to items (see also: Topics vs. items)
    • Make topics - convert all elements to topics
  • Forgetting index - change the forgetting index of all elements
    • Set forgetting index - assign a given forgetting index to all elements
    • Default forgetting index - make all elements use the default forgetting index. The default forgetting index is set with Tools : Options : Learning : Forgetting index
  • Ordinal - change the ordinal number of all elements
    • Set ordinal - give all elements the same given 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
    • Set difficulty ordinal - give all elements ordinals derived from item difficulty (easier items will get lower ordinals). This makes it possible, for example, to sort the pending queue in such a way that easy elements come first in learning
    • 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 of all elements
  • Template - template operations
    • Apply template - apply a selected template to all elements in a given branch. Unlike in earlier versions of SuperMemo, this operation is reversible. You can always apply a different template or use Detach template on element pop-up menu to remove the applied template from individual items
    • Merge with template - merge all elements with a given template (see Using templates). This operations is similar to Apply template but it is not reversible
    • Add template - add a template to all elements (see Using templates)
  • Count - count all elements matching some criteria in the whole set of elements
    • Items - count all items (see also: Topics vs. items)

    • Pending - count all pending elements
    • Dismissed - count all dismissed elements
    • Burden - count the statistics that indicate how much the considered elements contribute to the your learning workload (e.g. what proportion of all memorized items is included in the set, what proportion of all repetitions is contributed by the set, etc.)
  • Set title - assign a given title to all elements
• Close - close the browser

FAQ

Postpone factor determines how much intervals will increase (#4864)
Question:
What is the meaning of the parameter I need to input at Postpone?
Answer:
If you use 1.1, all intervals of outstanding elements in the selected subset will be increased by 10% (i.e. multiplied by 1.1)
