Registries are sorted sets of objects used in SuperMemo such as texts, images, sounds, fonts, etc.
By using registries, SuperMemo reduces the overall size of knowledge collections and makes it easy to reuse objects already introduced into the current collection. For more information about registries see: Using registries.

All existing registries can be accessed on the Search submenu of the main window.
A registry window is used to access individual members of a registry and is composed of the following panes:

• caption (caption of the window) - name of the registry and the total number of registry members
• toolbar (at the top) - button providing mouse shortcuts to the most often used registry operations
• editing field (under the toolbar) - field used in incremental search, i.e. searching for members by typing in initial characters of their names
• list of member names (left side of the window) - alphabetically sorted list of names of individual registry members
• object field (top of the right side of the window) - field that is used to display the object that is currently selected in the list of members (on the left side). In some registries this field is empty (e.g. sound registry, template registry, program registry, etc.) or is divided into two parts (e.g. text registry displays text translations, lexical registry displays phonetic transcription of individual words, translation registry displays the original texts, etc.)
• element list (bottom of the right side) - upon clicking the button List at the bottom of the registry window, the element list is filled out with all elements that use a given registry member. If the number of elements that use the member is greater than the maximum number allowed by SuperMemo, only a subset of elements will be displayed
• status bar (bottom of the window above editing buttons) - information about the currently selected member: registry index (i.e. the ordinal position of the registry member in the registry), number of elements that use the member, physical position in the registry, number of the filespace slot (if any), and path to the registry member file (if relevant). The filespace slot is a numbered position of a file in the elements directory. The first file will get the slot one, second slot two, etc. (e.g. 1.bmp, 2.htm, 3.wav, etc.).
• editing buttons (bottom of the window):
  • List - list the elements that use the currently selected registry member (the list is displayed in the element list at the bottom of the right side of the window)
  • Go to - go to the first element using the currently selected registry member
  • Browse - display all elements that use the currently selected registry member in an element browser. Note that the Browse button on the toolbar can be used to display all elements that use all registry members belonging to the current subset
  • Link - link the currently selected registry member with the requesting source (e.g. if you choose Links : Registry member on a sound component pop-up menu, the component will be linked with a sound object associated with the sound registry member selected at the moment of pressing Link). Link is absent from the template registry as template use is not registered with elements
  • Apply - (only in the template registry) apply the selected template to the current element (only if Apply template was chosen)
  • Add - add a new registry member to the registry
  • Rename - change the name of the currently selected registry member
  • Delete - delete the currently selected registry member. Note that the associated registry object, e.g. sound file, font, etc. will also be deleted (unless it is stored on CD-ROM)

Professional level

Right click over the registry window opens the registry pop-up menu with advanced operations on the registry.

(Dusko Ivanisevic, New Zealand, Oct 1, 1998)
Question:
How can I add phonetic transcription to some words?
Answer:
Press Ctrl+Alt+P and type in the word and its transcription. If the transcription dialog does not appear, you have not chosen phonetic transcription in Options. In such a case do the following:

1. Choose Tools : Options : Language : Phonetic transcription
2. Select ready-made transcription file or type in a name for new phonetic transcription registry (in the latter case, you will be building phonetic transcription registry from scratch)
3. If necessary, choose Font on the left to select phonetic transcription font (e.g. IPA font available from Advanced English)
4. Once a given word appears on the screen, press Alt+Y to transliterate all texts (or use on-mouse-move transliteration)
