;node
:one [[Glossary:Element|element]] in the [[Glossary:Knowledge_tree|knowledge tree]] presented in the [[Glossary:Contents_window|'''Contents''' window]] (a single [[Glossary:Item|item]], [[Glossary:Topic|topic]], [[Glossary:Concept|concept]] or [[Glossary:Task|task]] in the [[Glossary:Collection|collection]]). You can add new '''nodes''' with '''Add''' and '''Insert''' (''Ins'') at the bottom of the [[Glossary:Contents_window|'''Contents''' window]], or with options on the [[Edit menu|'''Edit''']] submenu of the [[main menu]]. If a '''node''' does not have [[Glossary:Child|children]], it is called a [[Glossary:Leaf|leaf]]. If the '''node''' has [[Glossary:Child|children]], it is called a [[Glossary:Branch|branch]]. If a '''node''' is used as a container for other nodes, it may also be called a '''folder'''. The [[contents menu]] provides some [[Subset operations|operations on entire branches]] such as: '''Learn''', '''Review all''', '''Statistics''', etc.

;branch
:in the [[Glossary:Contents_window|'''Contents''' window]], an [[Glossary:Element|element]] in the [[Glossary:Knowledge_tree|knowledge tree]] with all its [[Glossary:Descendant|descendants]] (incl. its [[Glossary:Child|children]]). All [[Glossary:Element|elements]] in a '''branch''' can be processed with [[subset operations]]. For example, if you would like to review your physics material before an exam, you could select the ''Physics'' '''branch''' in the [[Glossary:Contents_window|'''Contents''' window]], and click '''Learn''' (''Ctrl+L'') at the bottom of the window. You can add new '''branches''' with '''Add''' and '''Insert''' (''Ins'') in the [[Glossary:Contents_window|'''Contents''' window]]. A '''branch''' that is built automatically by adding [[Glossary:Element|elements]] to a [[Glossary:Concept|concept]] is called a [[Glossary:Concept_group|concept group]]. All [[Glossary:Concept|concepts]] are associated with their own '''branches/groups'''. By analogy to Windows, when a branch has no content and is use solely to hold other branches or elements, it may be called a '''folder'''.

Glossary:Element

Ozzie:

;element
:single page of information stored in [[Glossary:SuperMemo|SuperMemo]] (e.g. an article, a question-answer pair, etc.). All '''elements''' kept together are called a [[Glossary:Collection|collection]]. '''Elements''' may have the form of [[Glossary:Topic|topics]] (articles, [[Glossary:Extract|extracts]], summaries, etc.), [[Glossary:Item|items]] (testing material), [[Glossary:Concept|concepts]] (general ideas used in semantic learning), or [[Glossary:Task|tasks]] ('''elements''' representing to-do jobs). A [[Glossary:Topic|topic]] presents a larger part of the learning material, e.g. an article about the greenhouse effect. [[Glossary:Item|Items]] provide specific testing questions, e.g. ''How thick is the cerebral cortex?'' In the simplest case, [[Glossary:Topic|topics]] have the form of a page of text while [[Glossary:Item|items]] are formulated as questions and answers (see: [[Items, topics, concepts, and tasks|Topics vs. Items]]). Every '''element''' is represented in the [[Glossary:Contents_window|'''Contents''' window]] as a single [[Glossary:Leaf|leaf]] or branch of the [[Glossary:Knowledge_tree|knowledge tree]]. The content of individual '''elements''' is displayed in the [[Glossary:Element_window|element window]]. Read more: [[Items, topics, concepts, and tasks]]

Learning tab in Options

Ozzie:

'''Learning''' tab in '''[[Toolkit menu|Toolkit]] : [[Options]]''' (''Alt+O'') provides options affecting the way you learn:

[[Image:Options learning.jpg|center|800px|SuperMemo: Toolkit : Options : Learning tab]]

This is the interpretation of individual fields:

*'''Forgetting index''' determines the default [[Glossary:requested_forgetting_index|requested forgetting index]]. Forgetting index determines the speed of learning. When you first run SuperMemo, it is set to 10%. This means that SuperMemo will tune the learning process in such a way that you will stand a 10% chance of forgetting any given [[Glossary:Item|item]] at repetition. You can reduce the forgetting index to 3% at the cost of a significant slow-down of the learning process. You can also increase it up to 20% to greatly increase the [[Glossary:Acquisition_rate|speed of learning]] at the cost of [[Glossary:Retention|knowledge retention]]. Increasing the forgetting index further makes little sense as both retention and the speed of learning will decrease (you can read about it in [http://super-memory.com/articles/theory.htm Theoretical aspects of SuperMemo] or see it for yourself by using '''[[Toolkit menu|Toolkit]] : [[Toolkit menu#Statistics|Statistics]] : Simulation'''). All individual [[Glossary:Item|items]] can have their individual forgetting index set with '''[[Element menu#Edit|Edit]] : [[Element parameters|Edit parameters]]''' on the [[element menu]] (''Ctrl+Shift+P''). Read more: [[Forgetting index]]
*'''Always randomize final drill''' - scramble the sequence of repetitions in the [[Glossary:Final_drill|final drill]] before moving to the final drill stage
*'''Skip final drill''' - do not create the [[Glossary:Final_drill_queue|final drill queue]]. [[Glossary:Final_drill|Final drill]] must always be considered of lower priority than reviewing the [[Glossary:Outstanding_material|outstanding material]]. For that reason, in a heavily overloaded incremental reading process you may come to a point where your learning sessions always end with '''[[Postpone]]''' (or start with '''[[Glossary:Auto-postpone|Auto-postpone]]'''). If this is the case, building the [[Glossary:Final_drill_queue|final drill queue]] makes little sense
*'''Midnight shift''' - the number of hours after midnight on which the new repetition day begins. For your convenience you should put the midnight-clock-shift value to the middle of your average night. For example, if your average sleeping hours are 23:00 - 7:00 (i.e. 11 p.m. - 7 a.m.), the middle of your night comes at 3 a.m. If you then set your midnight shift at 3 a.m. (slider at 3), you are least likely to be in a situation when you need to change the midnight clock shift to correctly execute repetitions belonging to a given waking day. If on occasion you come back home late at 2:30 a.m. and are still able to make repetitions, SuperMemo will behave like there was no date change at midnight. On the other hand, if you wake up at 3:30 a.m. and decide to make repetitions at that time, SuperMemo will already consider those repetitions as belonging to the new day. Midnight clock shift is extended to 16 hours for people in shift work and those who work in unusual hours (e.g. as a result of [http://super-memory.com/articles/sleep.htm DSPS or ASPS sleep disorders]). The change of date will not occur until you restart SuperMemo. For that reason, you should always close SuperMemo for the night
*'''Algorithm SM-18 Alerts''' - alert on interval discrepancies large enough (in percent) for [[Glossary:Interval|intervals]] long enough (in days) as compared with Algorithm SM-15:
**'''Difference [%]''' - raise alert when interval difference (in percent) as compared with Algorithm SM-15 is equal or larger than the specified amount
**'''Interval [days]''' - do not raise an alert for intervals shorter than the specified amount
**'''Factor''' - raise alert when interval quotient as compared with Algorithm SM-15 is larger than the specified amount

Options

Ozzie:

'''[[Toolkit menu| Toolkit]] : Options''' on the [[main menu]] opens the options dialog that makes it possible to customize SuperMemo and the learning process. You can open this dialog in levels below the middle level with ''Alt+O'' (i.e. even if the [[Toolkit menu|'''Toolkit''']] option is not available on the [[main menu]]).

'''Options''' dialog includes the following tabs:

* [[Learning tab in Options | '''Learning''']] - options affecting the learning process such as: [[Forgetting index|speed of learning]], working hours, [[SuperMemo Algorithm|Algorithm SM-17]] reporting, etc.
* [[Access tab in Options | '''Access''']] - options affecting access to data: CD/DVD path, [[Glossary:Level|difficulty level]], [[Glossary:Collection|collection]] password, etc.
* [[Language tab in Options | '''Language''']] - localization options such as: language to which the current [[Glossary:Collection|collection]] is translated, [[Localization table | SuperMemo interface language]], strings used in translating the interface, etc.
* [[SuperMemo tab in Options | '''SuperMemo''']] - other options such as: [[Glossary:Knowledge_tree|knowledge tree]]'s [[Glossary:Branch|branch]] [[Glossary:Child|children]] limit, background image, sound feedback, etc.
* [[Mouse tab in Options | '''Mouse''']] - interpretation of mouse behavior. For example, how [[Glossary:Component|components]] are edited or translated with the mouse, etc.
* '''[[Leeches]]''' - options that help you eliminate wrongly formulated [[Glossary:Item|items]] from the learning process. If you choose '''Wizard''', all ill-structured [[Glossary:Item|items]] will open a [[Leeches#Leech_Alert_Wizard|leech manager dialog]] that will help you choose optimum processing steps to eliminate problems with difficult [[Glossary:Item|items]]
* [[Fonts tab in Options | '''Fonts''']] - fonts used in SuperMemo interface, in questions, in answers, in the [[Contents|'''Contents''' window]], etc.

[[Image:options_learning.jpg|center|center|SuperMemo: Toolkit : Options : Learning tab]]

Global options of SuperMemo are stored in the file ''supermemo.ini'' in the SuperMemo subfolder ''BIN''. Options that affect only the current [[Glossary:Collection | collection]] are stored in the file ''collection.ini'' in the [[Glossary:Collection|collection]] subfolder (named in the same way as the [[Glossary:Collection|collection]]). '''[[Toolkit menu|Toolkit]] : [[Toolkit menu#Options|Options]]''' will modify both these files and change relevant settings
